Does anyone know the title

I think they are either stepbrothers or adoptive brothers. Uke is younger than seme. Uke is in love with seme. He studied hard for highschool and dropped a bomb hes going to boarding school in the city (to avoid his older brother) to his brother surprised and displeased. In his dorm, he caught his roommate on a gay dating app. I cant remember much but he fought with his brother and ran to his roommates house
