My Stepbrother Is My Favourite Novelist!?

Kei is a reclusive novelist who has never experienced romance, so when his editor demands he write a Boys' Love story, he's utterly lost. Enter Kairi, his new stepbrother—a sharp-tongued, mischievous whirlwind who moves in after their parents' marriage. At first, Kei sees Kairi as an annoying disruption, but Kairi volunteers to become his 'romance tutor,' staging absurdly cute scenarios to help Kei understand love. What begins as a clumsy, comedic experiment slowly blossoms into genuine feelings, blurring the lines between research and reality. With only 38 minutes of runtime, this Japanese web series packs surprising emotional depth, awkward charm, and a sweet message about finding connection in the most unexpected places. It's a heartfelt, low-budget gem that celebrates the messy, funny journey of self-discovery.
