Yonosuke happily grew up with three girls. They became the best of friends and had the best times of their lives. He eventually became romantically aware of them when they all grew up. The girls grew up in all the right ways. Yonosuke assumes they only see him as a friend while he buries his interest in them. We’ll see if he realizes how they really feel when You Can’t Be in a Rom-Com with Your Childhood Friends! (Osananajimi to wa Love Comedy ni Naranai) premieres sometime in January 2026.
Shinya Misu released the original You Can’t Be in a Rom-Com with Your Childhood Friends! manga series on March 22nd, 2022. Kodansha has since published eighteen volumes in Magazine Pocket.

The three rom-com childhood friends are as follows:



- Shio Minamo — Rin Kusumi (Lauren Laraiya du Luvierte from Skeleton Knight in Another World). Yonosuke’s next-door neighbor, who gets as close to him as possible.
- Akari Hiodoshi — Yu Serizawa (Mini Yaemori from Rent-A-Girlfriend). Yonosuke’s tsundere childhood friend.
- Runa Tsukimi — Sae Hiratsuka (Lala from Beheneko: The Elf-Girl’s Cat is Secretly an S-Ranked Monster!). Yonosuke’s shorter yet older childhood friend.
Tezuka Productions maintains a home page and a Twitter (X) page to promote You Can’t Be in a Rom-Com with Your Childhood Friends!. You can find more information about the series and the key visuals at those sites.







You Can’t Be in a Rom-Com with Your Childhood Friends! We’ll See About That
Yonosuke Sakai was lucky enough to grow up with three cute girls. They maintained their close relationship from childhood to high school. It was around then that they all became aware of one another. Yonosuke saw his friends as girls with well-rounded figures. However, he kept his thoughts and feelings to himself. As much as he would like to get closer to them, he assumes that they only see him as a friend and nothing more.






However, Shio, Akari, and Runa all see Yonosuke as a boy. They all want to get closer to him and start romantic relationships. However, they believe he only sees them as friends. Shio practically throws herself at him. She’s well-positioned to do so, after all. She lives next to him and she’s agile enough to climb through his window to sleep beside him. Shio has also used her feminine wiles to stir Yonosuke’s heart. Her plans work, of course, but Yonosuke’s misunderstanding of her feelings prevents him from acting. The other girls will have to up their game to win him over.
