forgot another OTL

Uke goes to bar possibly to look for a man or something and gets his drink drugged and starts feeling sick so goes to bathroom helped by the guy who gave him the drink and when in toilet gets attacked by the guy and has his ass touched. Feels disgusted by it and tries to fight back but has no strength too. Seme intervenes and helps uke out.
I think uke may have been told not to go there or knows the seme

who needs drugs when you got yaoi
