The older guy (bottom) is a gay and has a coffeshop. The younger blond top is a student and a hetero. The bottom notices that when the top is in the coffeshop, there are more clients so he offers him a part time job. The bottom also has a toxic ex who cheated with a woman and married her, after the years he tries to get back with mc.
The art is specific, yaoi. They are neighbors, their relationship was bad at the beginning. The mc is a black haired student, the ml is a blond guy. The blond guy lies that he lost all his fortune in stocks, but actually he is rich, later he lied that he succeeded in stocks when the mc needed money. Their lips were really thick.
