Douluo, To My Childhood

Dedicated to my childhood and youth. There's a CP, no System, transmigration but no rebirth, no cheat powers, and two protagonists. The characters' nicknames and classes come from my school days. I'll also write in some characters from childhood games, but I'm only borrowing their names. The world is based on the real world, with martial spirits added. It has its own independent worldbuilding, and a divine realm exists, of course.
