Help finding this manhwa

I think it’s BL. Don’t remember the plot but I do remember a scene from it. MC rents a cheap place in an apartment complex that’s near the place he works at. He has two neighbors. One is a stalker (ML’s stalker, I believe) who had an encounter with him and is always complaining about the noise at his place. The other is a girl studying for something. MC tries to befriend the girl by putting macarons on her door handle. But the next day, the macarons are eaten and there is trash on his door handle. Later it is revealed the girl is allergic to egg(?) or sugar(?), and the stalker stole the macarons. That’s all I remember. Thanks!
