This is the 3rd time

I need help finding this yaoi manhwa but I ma really surprised how the hell I can't find since it's so popular
The mc is like some sort of therapist or something who helps people with like mental issues, I think he was married but he divorced because he wanted them to be safe since there were like people going after him, and then this mf comes right outside his window of the MC's car after he was done with work and proceeds to smear the blood of someone he just killed idk if he did that or just stared at him, I faintly remember someone waring him of a killer, of course the killer is the seme and he comes to the MC's work office at night and then tell him to help him, I remember him calling the mc doctor, I think most people could know after this what manhwa I am talking about, the seme is an arsonist and he seems to really like fire like way too much, he's tan or dark skinned, the art style is kind of realistic and it's really nice
