I have a question. Does anyone know the name of a bl story where a guy behind to work in a science lab with this one guy who is trying to create this like flowery plant smell or something I can't remember what it is he's trying to create but the guy who starts working with him finds he smells good for some reason I think he can't handle smells but he's okay with this guy's smell I read something like that but I cannot for the life of me remember what it was called or what exactly it was about I just wrote what I vaguely remember from the book
