Kuroha's been waiting since childhood for Maru to see her, and the show knows exactly what that silence costs. Every comedic moment lands because it's built on the terrifying fact that the girl who loves him most has everything to lose if he finally looks her way. The premise sounds like every other romcom, but it's actually about what it means to be the person nobody chose yet, watching the person you chose chase someone else.
Maru Sueharu has been quietly admiring Kachi Shirokusa, an award-winning writer and the most captivating girl in his year, convinced she's completely out of his league. His carefully maintained secret crush shatters the moment he learns she's already dating someone else. Wallowing in disappointment, Maru finds an unexpected lifeline in Kuroha Shida, his childhood friend who's always been there with her infectious energy and genuine care. But Kuroha isn't just offering sympathy. She casually drops a confession: she likes him, and she has a plan to "get revenge" on the situation by helping him win Kachi over instead. What unfolds is a chaotic love triangle where Kuroha orchestrates schemes to derail Kachi's relationship while simultaneously testing how serious Maru actually is about his feelings. Part strategic comedy, part genuine emotional scramble, the series watches these three characters collide as hidden histories surface and everyone's true motivations get questioned. Childhood bonds, romantic idealization, and the messy reality of actual human connection crash into one another.
