LOOKING FOR THIS YAOI MANGA

so they live in together in a luxurious apartment because of a mutual friend, the seme has blonde hair and is an architect, the uke I think had no where to go so he asked this friend and his friend gladly let him stay at his apartment for free until he finds a new place, his friend is an owner of a bar and is very rich, the uke has black hair. So the uke didn’t expect that there was another person living in that apartment which is the seme. And that’s all that I can remember at most, please help
