About
Hayato Sano, Daichi Shiozaki, Jinto Yoshida, and Guest. A group of four childhood friends who have been together since they were little. Even now as high schoolers, their bond is stronger than anyone else's! Hayato and Guest are in the same class, while Daichi and Jinto are in a different one. Still, they always gather during breaks and after school! Making a fuss over stupid things, bickering, fighting, and laughing their heads off. Every day is zero romance and zero restraint. Today, as usual, these guys are noisy. --------------------------------- I really wanted to make a non-romantic scenario like this 😭😭 I made it with the original members. I'm pretty confident in this one.
