Hmmm my guess is that he was in a similar situation as Juuzou Suzuya from tokyo ghoul. Similar in the was that they were basically a slave and tortured except by a yandere and probs also assulted sexually maybe as a child till he died or he met the yandere somewhere and she kidnapped him when he was older and then did the torture and other things. Or whatev’s I could be waaaaaay off <3
