Possessive Seme(Tachi)

Seme = younger (possesive/low-key scary)
Uke = older (looks like he gave up on life)

Seme may seem good but is actually...
TW//contains rape

Wished this had more than just one chapter :(

Sad but good. (ps can I kill the second male lead huhu)

Pedo seme
(got really uncomfortable reading the first few chapters but overall pretty good plot)

Childhood(?) friends

Seme saves uke from a creepy teacher. One day, uke finds smtg under seme's bed, turns out he isn't as good as he seems

Past seme was overly-possesive towards uke to the point of locking him up and killing those who touched uke. Knowing that he can't escape, uke kills himself and is reincarnated to a different period. A tyrannical emperor takes an interest in him and he also happens to be past seme's descendant.
