I'll explain that scene with baby
So you remember when shaman casted spell on emperor so he can find uke in every life? Back then uke's soul begged shaman not to do it, shaman felt bad and because he sinned he took his own life to repay uke, now it's just my theory but I think after emperor died his soul was trapped in world where he can have happy ending with uke by shaman but emperor knew every time something was wrong so whenever he realized another scenario began and finally tired of it, emperor took his own life to escape that place and reincarnate
