I totally understand why the duke is pissed. He gets seduced and taken advantage by him, and he has no recollection, while he remembers it clearly. Of course that’s gonna piss anyone off, especially when the duke didn’t wanna do it in the first place but went along with it eventually.
Buuuttt~ he did react and handled it poorly. Instead of being pissed and forcing him to remember, he should’ve been more smooth about it and seduced him back. Forcing him only makes him resistant and thus pisses the duke off even more lol. You gotta play the game duuukkee. Come on! Lol (๑•ㅂ•)و✧
