about the seme

ok so after finding out more abt this, this reminds me of that one bl manhwa with split personality (ion remember the name), but the seme here is actually a pretty decent guy (he's srsly a puppy, he has known our uke a long time ago when they were in orphanage ig, and were pretty close to eo too), he's doing things unconsciously at night and won't remember anything the morning after, he was literally asking uke "what's wrong with ur face ??" (abt the piercing incident), the summary already said abt his condition btw, and so the seme is like a two different person during the day and night— uke and seme make up when he's in his day personality, but there'll be some misunderstanding from their past on orphanage (seme has no one, and one day there was this couple that wanted to adopt uke, so seme went to the couple and was crying and told them "he's a bad kid, don't adopt him" smth like that bcz if uke left, who will be by his side right ? and btw seme is an illegitimate child of this one rich dude, so he's the one that left first if I remember correctly bcz the dude took him in)— back to the present, seme was crying after uke said smth like "u talked behind my back.. if it wasn't bcz of u, I would've been adopted" (AGH I FORGOT) and seme was planning to ask for uke's forgiveness, he was so depressed that he switched personality— so warning ahead, in chapter 10, seme's night personality was being too possessive and mad when uke said he'll leave him so he grape the uke again, there'll be a lot of blood, like A LOT, and that morning when seme woke up, he was genuinely confused why uke's naked and bleeding + tied up in the bed, the only thing he remembers is, he wants to apologize abt their past
