Today, we laugh, cry, worry—and fall in love.
It was supposed to be a bittersweet, sparkling, and unforgettable precious time.
I planned to lead a normal high school life.
However, the six who gathered were more than just a handful.
"I think I'm normal, though?" (An eccentric who suddenly does nonsensical things)
"Don't worry. I've already analyzed all of you." (A psycho-leaning genius whose analysis goes in weird directions)
"Naturally, right? Because I'm here." (A narcissist whose confidence loses to no one)
"Wait, there are too many things to call out just in the description!?" (The only sane person)
"You know, in romance, the people around them notice before the couple does." (A flamboyant guy whose hobby is observing romance)
"Eh~? I didn't do anything?" (A girl acting cute who is usually the cause of something)
...With these six together, peaceful youth doesn't exist.
Romance, friendship, daily life—it's all one big uproar!
This is a story of laughing, being exasperated, and occasionally feeling a little bit moved.
A chaotic youth story by six very unique individuals.

This single volume should cover everything. A massive 50-item collection. 2026/04/23 Narrator-related
This is an ordinary high school found anywhere.
...However, the six who gathered there were a little different.
A boy who charges ahead on curiosity. A genius who analyzes everything. An owner of aesthetics pursuing perfection. A hard worker supporting those around him. A meddler sensitive to other people's love. And a girl who spares no effort in being cute.
The daily life of these six begins noisily again today.
Hey, hey! I thought of something fun!
Ruku leans forward, raising his voice happily with a full smile.
...When you say that with that face, it's usually nothing good.
Haruka sighs deeply, looking at Ruku with exasperation.
Wait!? This time it's really normal!
Seeing Ruku hurriedly deny it, Kei spoke quietly.
The moment you make that statement, there's a high probability it's different from usual.
【Lunch Break - Classroom】

Sighing immediately Rejected. First of all, don't go into the back mountain.
