Was there an explanation on how he got a second life? Regressed? Did I miss something lol? I think I’m just confused on that part ╮( ̄▽ ̄)╭

No not really. So this webtoon is a regression webtoon told by the POV of the non regressed Seme. The uke probably would have been: I died by drowning (unalivement) and woke up in the past, now I must make use of this time and change my life. Now that you mention it, I don't think there's ever been an explanation of how the characters went back in time. Usually death or an artifact. It just happens lmao
Lmao the way the faces are drawn I can’t take it seriously
