Danjo no Yuujou wa Seiritsu suru? (Iya, Shinai!!)

In a quiet high school routine built on inside jokes and shared after-school time, two best friends treat “just friends” as a promise they can rely on.

Yuu pours his feelings into handmade accessories inspired by flowers, while Himari becomes the steady support who helps him put his work out into the world. Their balance shifts when someone from Yuu’s past returns and sparks new attention around him—attention that makes friendly boundaries feel less certain. With comedy and tender awkwardness, Danjo no Yuujou wa Seiritsu suru? (Iya, Shinai!!) follows a trio of teens as admiration, ambition, and first-love confusion begin to overlap.
