Help me find a bl manhwa

I don’t remember the title, but it was about a way older uke with black hair taking care of the neighbour child or something, because the child was getting abused and the child was grey, light ish haired and grew obsessed with the uke and the obsession got so crazy he was hospitalised and lost his legs at some point idk..and the uke was working at the hospital because he was kicked out of his village or wherever he was living at… I don’t want to read that traumatising shit again, I just wanna know what it was called again,since I keep thinking about it for the past few days.
