Help!! I need help finding a yaoi manga

I'm trying to find this manga with a guy whos living with the seme. He cooks and cleans for him. The guy writes books and is famous. I also remember that the seme has a rival that specifically tries to get with the uke. The uke has younger brothers. The scene I remember the most is when there was a misunderstanding between them and he found out that the seme was hanging out with this guy so he avoided him until at the airport the seme was like no thats not how it is I love you
