Looking for a bl manga

All i could remember is that the uke was being stalked so a friend of his (which he had a crush on and is the seme) offered to stay with him in his apartment and they developed feelings found out the stalker was the uke’s next door neighbor who even placed listening devices inside his room etc etc but the plot twist is that that the uke is also obsessed with the seme and actually knew who the stalker was and only used the situation to get the seme. I read it long time ago and its been stuck in my head and ive been trying to find it :(
