He had suffered too much pain in his previous life. Between rebirth and falling into the hell of reincarnation, he chose to be reborn. He hoped that he could find his own happiness. Maybe it was a luxury hope, but he would not give up his ideals...
PS: The protagonist's heart is a bit dark, but most of them are mainly funny. Also, the author is only a middle school student, and now students' studies are the most important thing, so be prepared for the author to give up at any time!
