It starts off with a pretty boy with blonde hair, and he is a player. He ends up being dumped by his girlfriend with leads to him going to a bar, meeting a designer who he ends up (idk how) living with. This pretty boy is dead set on being straight frfr. The black haired designer is conflicted (i think). The blonde ends up being his assistant (idk how) and helps to build his business up pretty successfully. They fall in love somehow with a lil complications bc someone was (maybe) homophobic. i think the blonde was. some things happen but i forgot. they meet the blonde’s mom. Pls help i cant find it anywhere.
