Osamake: Romcom Where The Childhood Friend Won't Lose

Sueharu Maru has grown up alongside Kuroha Shida, one of Hozumino High School’s most admired girls. Bright, friendly, and doting in an older-sister sort of way, Kuroha attracts constant attention—so when she suddenly confesses her feelings to Sueharu, it catches him off guard. He turns her down, unable to see her romantically, especially with his heart still set on his first love: the school’s idol and celebrated author, Shirokusa Kachi.

After a chance encounter convinces Sueharu he might finally be able to reach Kachi, he learns she already has a boyfriend, leaving him crushed. That’s when Kuroha returns with an unexpected plan: the two of them should team up and get revenge.
