What Does It Mean That the Protagonist Is My Classmate?

Helo, babies, this is my first work. All the characters in it are prototypes (my classmates~). I have communicated that they all volunteered to be the characters in it. The world view will continue to grow in the later period~ I will update the novel according to daily life. I hope everyone likes it ✧₍^˶-˕-˵^₎✧
