If you searched for Captivated by You, you probably fell down a rabbit hole. Maybe you saw a clip of two quiet boys named Nikaido and Medaka on social media. Maybe you heard about a manga called Muchuu-sa, Kimi ni and wondered what it actually was. Or maybe you just watched the new 2025 anime and want to know how it ends. Whatever brought you here, you are in the right place.
Captivated, by You is a short, quiet, and surprisingly funny slice of life manga by the Japanese artist Yama Wayama. It is not a big, dramatic epic. It is a collection of small stories about high school students who feel a little strange, a little lonely, or a little misunderstood. It has since grown into a Japanese drama (2021) and a five episode anime (2025), both of which follow the same characters and the same quiet, warm story.

Quick Answer
Captivated, by You (Japanese: Muchuu-sa, Kimi ni) is a 2019 slice of life manga by Yama Wayama about students at an all boys Japanese high school. The story is split into two halves. The first half follows Hayashi Miyoshi, an odd and honest student who does strange little hobbies like counting stairs and drying sweet potatoes.
The second half follows Nikaidou Akira, a gloomy student rumored to be a bad omen, and his classmate Medaka Yuichi, who slowly becomes his friend. The manga was adapted into a 2021 Japanese drama and a 2025 five episode anime by Doga Kobo.
Book Overview and Background
Captivated, by You did not start as a normal published manga. Yama Wayama first drew it as a doujinshi, which is a self published, small run comic, and shared it at a fan convention called Comita in February 2019. It caught the attention of an editor at the manga magazine Comic Beam, who helped turn it into an official one volume release later that same year. That is a big deal in the manga world. It means the story was so charming that a professional publisher picked it up almost right away.
In the United States, Yen Press published an English translation, handled by translator Leighann Harvey and letterer Abigail Blackman. It came out as a single hardcover volume, which is unusual and shows the publisher believed in the book’s quality.
The genre blends comedy, slice of life, and gentle drama. There is no big villain and no major conflict. Instead, the story quietly studies school life, friendship, and what it feels like to be the “weird kid” in class. It is often compared to other character driven slice of life stories because it cares more about small, honest moments than big plot twists.
Important concepts to know before you start:
- The story is not one continuous plot. It is a set of connected short stories, told from multiple points of view.
- The first half and second half of the book focus on two completely different male leads.
- It is often mistaken for a straight up Boys Love (BL) story because of how close the male friendships get, but the author has said the real focus is friendship and identity, not romance for its own sake.
Spoiler-Free Summary
Captivated, by You takes place across two different schools. In the first half, the story follows Hayashi Miyoshi, a high school student who does not care what anyone thinks of him. He counts every staircase in the building, takes photos of ordinary street signs, and dries sweet potatoes on the classroom balcony like it is the most normal thing in the world. His classmates find him confusing at first, but one by one, they get pulled into his orbit and end up liking him for exactly who he is.
Partway through the book, the focus shifts. The second half introduces Nikaidou Akira, a student who has built a gloomy, dour façade on purpose. Rumors spread that he is a bad omen, cursed with strange, almost supernatural bad luck. Most students avoid him completely. But his classmate Medaka Yuichi is curious instead of scared, and slowly starts chipping away at Nikaidou’s mask.
Without spoiling the ending, the book closes with both storylines showing the same basic idea: the people we label as “weird” or “scary” are usually just being honest about who they are, and the real reward is the friendship that forms once someone bothers to actually look closer.
Full Summary (With Spoilers)
Part One: Hayashi’s Stories
The manga opens at an all boys school, where a strange new student named Hayashi Miyoshi becomes an instant topic of conversation. He is not strange in a scary way. He is strange in a completely open, honest way. He counts every single staircase in the school building for no real reason. He photographs ordinary street signs around town. He hangs sweet potatoes out to dry on the classroom balcony like it is a normal school activity.
Each of the first few chapters is told from a different classmate’s point of view. One student is dared to call Hayashi “cute” as a joke, and then has to deal with Hayashi taking the compliment completely seriously and asking about it again and again. Another chapter follows a girl who reads a book within the story (a novel called Iron by Iron) and posts a review of it online. She gets an unusual, thoughtful reply from a stranger, and when they finally meet in person, she realizes the stranger is Hayashi.
The common thread across every one of these short stories is the same: someone starts out confused or annoyed by Hayashi’s eccentric habits, but ends up genuinely liking him once they stop trying to figure him out and just accept him. By the end of his section, Hayashi has quietly built a small but loyal group of friends, including a classmate named Ema Joji, simply by refusing to pretend to be anyone other than himself.
Part Two: Nikaidou and Medaka’s Stories
The second half of the manga shifts to a different setting and a different pair of leads: Nikaidou Akira and Medaka Yuichi. Nikaidou has spent years perfecting a gloomy, dour façade. He barely speaks, avoids eye contact, and lets rumors spread that he is bad luck, even a bad omen with supernatural powers. Almost the entire school keeps their distance from him because of it.
Medaka, who sits behind Nikaidou in class, is the one exception. Instead of being scared off, he is curious. Slowly, chapter by chapter, Medaka starts noticing cracks in Nikaidou’s scary reputation. He learns that the “curse” stories are mostly coincidence and misunderstanding, and that underneath the persona, Nikaidou is actually thoughtful, a little awkward, and quietly funny.

The relationship builds through small, everyday moments rather than one big dramatic reveal. Medaka does not force Nikaidou to change or to open up faster than he is ready to. Instead, their friendship grows through shared class time, offhand conversations, and eventually a school trip to Okinawa (a moment expanded on in the anime’s finale), where Nikaidou is grouped with Medaka and his friends Sakura and Zaki. Even here, the story avoids forcing constant romantic or dramatic moments between the two leads. Nikaidou still gets quiet time alone, and Medaka never pressures him to be someone he is not.
By the end of the book, Nikaidou’s “bad omen” reputation has softened, not because he suddenly became popular, but because one person cared enough to look past the rumors. The story ends on the same quiet, hopeful note as Hayashi’s half: being your true self, even an odd or guarded version of it, is what actually draws real friendship toward you.
Main Characters
Character: Hayashi Miyoshi
Role and Arc: Hayashi is the eccentric student who anchors the manga’s first half. He does not have a dramatic character arc in the traditional sense. His “growth” is really about the people around him growing to accept him. He stays exactly the same frank, guileless person from start to finish, and that consistency is the whole point. He represents individuality in a school culture that rewards conformity.
Character: Ema Joji
Role and Arc: Ema is one of the classmates pulled into Hayashi’s orbit. He starts off puzzled by Hayashi’s habits but becomes one of his steady friends, representing how curiosity can turn into real connection when someone gives an unusual person a real chance.
Character: Nikaidou Akira
Role and Arc: Nikaidou anchors the manga’s second half. He deliberately built a scary persona to keep classmates away, likely to avoid being hurt or judged. His arc is about slowly lowering his guard as Medaka proves, again and again, that he is not going anywhere. He is the emotional heart of the “hidden personality” theme that runs through the whole book.
Character: Medaka Yuichi
Role and Arc: Medaka is the responsible, curious student who sits behind Nikaidou. He does not try to “fix” Nikaidou or force him to change. Instead, he simply keeps showing up, asking honest questions, and treating Nikaidou like a normal classmate. His arc shows that patience and consistency, not grand gestures, are what real friendship is built on.
Supporting Characters
Characters like Sakura and Zaki (Medaka’s friends) and Matsuya and Arakawa (classmates in Hayashi’s stories) round out the ensemble cast. They are not deeply explored on their own, but they matter because their reactions (confusion, teasing, eventually acceptance) mirror how an audience might react to Hayashi and Nikaidou too.
Character Relationships
Captivated, by You is really a story about pairs, and understanding these relationships is key to understanding the whole series.
- Hayashi and his classmates: Not one single friendship, but a pattern. Different students each get their own short story where they misunderstand, then understand, Hayashi. Together, these stories build the idea that honesty is magnetic, even when it looks odd from the outside.
- Hayashi and Ema: Represents the more settled, ongoing friendship that comes out of Hayashi’s constant honesty. Ema becomes a steady presence rather than a one-chapter cameo.
- Nikaidou and Medaka: The manga’s most discussed character relationship, often searched as “Nikaido and Medaka” or “MedaNika.” Their bond grows from curiosity, to familiarity, to genuine care, without ever needing a single big confession scene to feel real. This slow-burn, low-drama style is a major reason fans describe the pairing as BL-adjacent rather than confirmed romance.
- Nikaidou and the rest of the school: A one-sided “relationship” built entirely on rumors and social stigma. This contrast (what the school believes vs. who Nikaidou actually is) is what makes Medaka’s patience feel so meaningful by comparison.
Key Themes Explained
Individuality vs. Conformity
The biggest theme in Captivated, by You is the tension between individuality and conformity in Japanese school life. Hayashi never changes who he is to fit in, and the story rewards that choice by giving him real friends anyway. Nikaidou does the opposite: he hides his true self behind a scary mask to avoid standing out, and the story shows how exhausting and lonely that choice becomes. Together, these two halves argue the same point from different angles: pretending to be someone else costs more than it protects.
Hidden Personalities and True Selves
Both lead characters wear a kind of “mask.” Hayashi’s mask is his odd hobbies, which some classmates mistake for him not caring what people think. Nikaidou’s mask is his gloomy, dour façade, built specifically to keep people away. The story’s emotional payoff comes from watching other characters look past these masks. This theme speaks directly to teenage experience, where so much energy goes into managing how others see you.
Friendship Built on Patience, Not Drama
Unlike many school stories that build friendship or romance through big, dramatic moments, Captivated, by You builds connection through small, repeated, ordinary interactions. Medaka does not save Nikaidou from a crisis. He just keeps sitting near him, asking normal questions, and refusing to be scared off by rumors. This makes the friendship dynamics in the story feel realistic rather than exaggerated, which is a big reason fans call it grounded storytelling.
Social Stigma and Rumor Culture
Nikaidou’s storyline is really a case study in how rumors spread and calcify inside a closed environment like a school. Nobody actually investigates whether Nikaidou is truly a bad omen. The label just sticks because it is easier to repeat a rumor than to question it. Medaka is the only one who treats the rumor as a question instead of a fact, and that single choice changes everything for Nikaidou.
Coming of Age Through Small Moments
There is no single, huge “growing up” event in this book. No one moves away, no one nearly dies, no one falls into a dramatic love triangle. Instead, coming of age happens through counting stairs, drying sweet potatoes, a school trip, and quiet conversations. This is intentional. The theme is that growing up is mostly made of tiny, unremarkable moments that matter more than they seem to at the time.
Symbolism and Literary Devices
Sweet potatoes and street signs: Hayashi’s odd hobbies (drying sweet potatoes on the balcony, photographing street signs, counting stairs) are not just comic relief. They symbolize authenticity. He does things because he finds them interesting, full stop, with no concern for how they look to others. Every time a classmate laughs at these hobbies and then softens toward them, it mirrors how the reader is meant to react too.
Nikaidou’s “curse”: The rumor that Nikaidou brings bad luck functions as a symbol for how social stigma works in real life. It is vague, unprovable, and mostly kept alive by repetition rather than evidence, much like real-world rumors and stereotypes about people who seem different.
The book within the story (“Iron by Iron”): A minor but clever device. A character discovers Hayashi partly through an anonymous online book review, showing how genuine connection can form through honest communication, even before two people officially “know” each other.
Perspective shifts: Wayama’s choice to tell early chapters from multiple points of view is itself a literary device. It forces the reader to misjudge Hayashi the same way his classmates do, then correct that judgment, chapter by chapter. This structure is part of why the story avoids feeling like generic slice of life filler.
Manga vs. Anime vs. Japanese Drama: What’s the Difference?
The Manga (2019): Written and illustrated by Yama Wayama, released as a single completed volume through Comic Beam in Japan and Yen Press in English. This is the original source material and the shortest version of the story, told as a one-shot collection split into two halves.
The Japanese Drama (2021): A live-action adaptation that aired from January to February 2021, directed by Ayuko Tsukahara. It brought the manga’s characters to life with real actors and is sometimes discussed under names like Raiku in fan circles, alongside actor Riko Fukumoto. It was available internationally through platforms like Viki and WeTV.
The Anime (2025): A five episode anime produced by Doga Kobo, directed by Asami Nakatani and written by Yoshimi Narita, with music by Takurō Iga. It aired in Japan from August 21 to September 18, 2025, and was licensed internationally by Crunchyroll. The voice cast includes Kenshō Ono as Hayashi, Kōki Uchiyama as Ema, Nobuhiko Okamoto as Nikaidou, and Yūki Ono as Medaka. Because the manga is a one-shot with a limited number of chapters, the anime expands some scenes, most notably the school trip finale, to fill out its five-episode runtime.
If you want the original, most efficient version of the story, start with the manga. If you want to see the characters animated with voice acting and music, the 2025 anime is the easiest to access through Crunchyroll. The 2021 drama is best for viewers who specifically enjoy live-action Japanese school series.
