Please Help me find a yaoi manga

Ok so
I remember reading a yaoi manga that was about a guy who was the youngest in his family and all his older brothers were really smart, but he was the not as smart one and i think one day he got into a fight with his family so he ran away from home or something and he met the seme who i think worked at home as a novelist or something. Then they started to live together and at the end he went back to apologize to his family for getting into a fight with them and his family was super worried about the uke and they said it was ok if he was not as smart bc the dumb ones are the cutest.
