Help me find it

It's yaoi, about two coworkers. First one was black haired nerd and the onter one was brown haired handsome man. The nerd knew that the brown haired man slept with other men so he said he will blackmail him if he doesn't sleep with him so they slept and then the nerd gave the brown haired man roses and smth and he told him he loved him so they started to meet up. At the start the brown haired man found the nerd annoying but after some time he also started to like him and bought him clothes and helped him with makeover. (I forgot to add that if the nerd took of his glasses and put his hair down he would be handsome) The laste scene I remember is when they were in a bathtube and the brown haired man asked the nerd about his past and thought he lived with gangsers but in reality he did not. Anyways sorry if I made some mistakes, it was quite a while since I read that. Tysm for help
