Does anyone know what this manwha is?

I’m so sorry I read this a while ago so I don’t remember most of it but it was a bl manwha about a guy (a) who could see this other guy (b) no one else could see (I think he was a ghost but I don’t remember) and like he had a crush on this guy (c) but I remember the guy (c) was kind of rude to him (a) but the ghost?(b) could control the guys (a) body and when he did c would like act a lot nicer to the guy that’s all I can really remember I’m sorry I also think (a) was like unhealthy like as a kid but I don’t remember well I’m sorry
