Unzen Sensei is seen as a calm and collected man who is constantly looking to make his students grow into better and more fulfilled people.

Junta Shiraishi has just one goal: to experience youth to the fullest! But this is easier said than done. Junta is so socially invisible that people at school would swear he skipped class even when he’s sitting right behind them. Everything changes when Junta meets Nagisa Kubo. She’s the only person who pays Junta any attention, and her constant teasing is sure to turn Junta’s quiet life upside down because Kubo won’t let him be invisible!

First year high schooler Junta Shiraishi is a mob character who goes unnoticed even when he's standing right next to you. But his classmate, "heroine-level beauty" Kubo, always notices him and is there to tease him. Anyone can become special to someone, but it might be a little too early to call these feelings "love." Perhaps this story is still two-steps from being a romantic comedy--let's call it a sweet comedy where a background character becomes visible!
