I think the "him" from his past life cease to exist after reincarnating/regressing (or both)... Maybe his new parents only had one son in their past life(his newborn brother)... I don't think there's any switching going on but it would be interesting if there is and the other one becomes a villain and compete Seongguk...
i think his past self no longer exist. Bc of that scene where he watch TV and his brother/cousin or whatever the guy was is pushing his grandfather’s wheelchair and it says he was the one pushing that in his past life
Something is confusing me like where is the past him who are supposed to be 11-13 yrs old right now? He didn't even bring that topic up. Is that past him non existent anymore? Plus before he was regressed that child body who he possessed now, where his soul went to? Did they switch body?
