Somebody help meeeee!!!!! I've been wracking my brains for almost a day but I still can't find it!!!

Does anybody here know a shoujo manhwa where the MC acts as some kind of evil empress because the ML told her to, what i mean is that she acts all demanding and whatnot to deter the MLs enemies (?) Fuuuckkkkk i ain't even sure of what the story really is about now

Also I think there's a part where umm... The ML transforms as some kind of monster, a dragon i think

Fuck this shit, somebody pls help meಥ‿ಥ Just sending stories to me that is vaguely like the one i just described (word vomited) would be much appreciated
