what's that toxic crossdressing yaoi with ugly mc

i genuinely can't remember its name. The mc is kinda ugly and born in a house of omegas. He likes to crossdress. And he was uh rped because he tried to defend his brother or something who was rlly pretty in college. And he happened to be wearing some lingerie or something that day and was outed about it. He becomes a doctor in the future and finds ml in an alleyway and pretty sure he was there too where the assault happened. And it's a pretty shitty concept and really short like 20 chapters. But I suddenly remembered it and omg if I don't find its name I'm gonna go craxy it's driving me insane.
