Help me find this yaoi!

It was about a black hair, possessive Seme and blond, short, dumb, uke. The seme and uke are roommates/childhood friends/sex friends. The uke I think is an office worker? And the seme doesn't have a job, but instead spends his time taking care of the household chores for the uke. He's super super obsessed uke (to the point putting his own cum into ukes drinks) and somehow managed to convince uke into being sex friends with him so uke can gain experience? Uke is oblivious of his feelings but eventually comes to realize his love for him as well. The story spanned about two chapters I think and the new few chapters followed a different couple that I can't remember anything about.
