Help finding yaoi manga

I remember reading this manga but can't find it which is really bothering me. It was something along the lines of some dude who went to take care of another dude and he had kinda long isn hair, black. And he was an author. The boy worked an office job and no on knew about who he was taking care of? Also the black haired dude had stubble and was kinda untamed since he lost the will to keep writing til he met the other guy(mc). Also, mc met another guy this time like a blond ish color hair and he wanted to take mc from the other black haired dude. Can someone help me find this, sorry if it was vague, I tried adding as many details as possible but I don't really remember much. Please help ╥﹏╥

Another thing I remember was that mc introduced the black haired guy (I guess they were in a relationship??) but he introduced him to his family and he had I think 3 siblings, mc was the oldest and was trying to earn money to help the rest of his family. And one of the siblings didn't like the guy mc was dating but then came to accept him since mc chose him so the sibling supported his decision.
