The idea in math class, I don't know about other things..._(:з∠)_It's probably a love cookie
The male protagonist's name is jj, and the rare characters cannot be displayed... Just add a "san" to the prefix of "zhu". To be honest, I don't want to change it... Alas, it has been changed to "san" which means "three o'clock water".
A love story between a somewhat charming female protagonist and a stupid male protagonist.
