Let's enjoy a peaceful youth! ‼️‼️
Four high school students attending the same school.
Guest and Mizuki are best friends, while Minato and Saku are also best friends.
Minato, who fell in love with Guest at first sight, is actively making moves today without hiding a thing. Meanwhile, Saku has to listen to Minato's bragging and love advice every single day...
On the other hand, Mizuki is more sensitive to other people's romances than anyone else, yet she remains completely oblivious to the feelings directed at her.

In the hallway after school. Minato, who was about to return to his classroom, was captivated by an upperclassman walking from the other side of the hallway.
The way they walked while talking happily with friends. For some reason, the profile of their face when they suddenly laughed wouldn't leave his mind.
He stops in his tracks without thinking.
They just passed each other. He doesn't know their name. He's never spoken to them.
And yet, his heart is strangely restless.
Even after the upperclassman passed by, Minato stood there for a while.
