A high school kid dyes his hair blonde to match his teacher's anime crush, and the show never stops being funny about how committed he is to this bit. The comedy writes itself because both characters are locked into their own logic, and watching them collide is genuinely hilarious. It's a slideshow with a shoestring budget, which means you're reading the jokes instead of watching animation, but the jokes are good enough that you don't care.
Murai is utterly convinced he's in love with Tanaka-sensei, his teacher and devoted otome game enthusiast. When he confesses, she shoots him down with brutal honesty: she's only attracted to the fictional men in her games, specifically the tall, blonde, aristocratic types. Nothing in real life compares. So Murai does what any determined high school boy would do: he dyes his hair blonde and cuts it short, transforming himself into a walking replica of Tanaka-sensei's favorite game character. It works. Kind of. Now she's flustered around him, caught between her gaming fantasies bleeding into reality and the awkwardness of having her student actively pursuing her. What follows is a chaotic back-and-forth of romantic persistence, embarrassing misunderstandings, and Tanaka-sensei constantly caught off-guard by her own contradictions. Murai refuses to accept defeat, while Tanaka-sensei struggles with the line between her fantasy world and actual responsibility. Neither of them is quite willing to admit what's really happening between them.
