Osamake: Romcom Where The Childhood Friend Won't Lose

When his crush says “no,” a childhood friend turns revenge into a twisted romance game.

Sueharu Maru has spent his whole life with Kuroha Shida, the charismatic, older‑sister‑type who’s the darling of Hozumino High. While Kuroha’s endless stream of admirers treats her like a celebrity, she’s always kept Sueharu close, assuming their bond will eventually blossom into something more. When she finally confesses, Sueharu bluntly turns her down, still fixated on his first crush: the school’s idol‑author, Shirokusa Kachi. He convinces himself that a chance encounter with Kachi could turn his fantasy into reality, only to discover she’s already in a steady relationship. Crushed and bewildered, Sueharu spirals into self‑pity until Kuroha, ever the schemer, offers a twisted pact—team up and make Kachi regret letting him slip away. What follows is a chaotic tug‑of‑war between earnest romantic longing and petty vengeance, all set against the backdrop of high‑school hallways, club activities, and the ever‑present pressure of teenage expectations. As Sueharu toggles between genuine affection for Kuroha and his lingering infatuation with Kachi, the series riffs on the classic love‑triangle trope while injecting a sharp, self‑aware humor that keeps the stakes both heartfelt and hilariously petty.

A lighthearted harem romcom where a former child actor juggles his childhood friend's fake-dating revenge plot, his crush on a school idol, and a chaotic love polygon. Expect comedic misunderstandings, mild fanservice, and a revenge-dating premise that leans into genre tropes rather than genuine darkness.
