Honestly this manga hits me deeper than any other manga , usually the tittle of rebirth is like you've gained some power and become OP immediately but this manga is different.

This hit me hard that i've cried for a whole 30 minutes while reading the "Parting" and "Departing" chapter , tbh this is the first manga i've been cried for and i never cried watching anime and reading some any manga but this is different

This manga is a MASTERPIECE , its the real SLICE OF LIFE genre that having some deep good shit to know like how life's work

Any other Anime / Manga its probably like cried over some romance , betrayal or any of it but this is NOWHERE NEAR that.

Im not gonna spoil anything but i just recommend this manga and the light novel.
