hm... there's one, https://www.mangago.zone/read-manga/i_ll_retire_after_saving_the_world/, but the MC is still looking for his younger self (I've only read 20 ch because I want to marinate it but so far so good)
I mean that happens in this https://www.mangago.zone/read-manga/life_completely_ruined/ but I don't think it's the vibe ur going for
I guess I didn't read well, lmao sry ╮(￣▽￣)╭
I've just finished reading this! Thx for recommending this amazing manwha!
Is there any manwhas where the MC goes back to the past but their past self also exists simultaneously? Sth similar to For My Own Good
