Simon, an ambitious movie director and a film fanatic, created a movie club for his school but no one join his club until a girl named Hannah joined the club and thought they can make a romance movie together except for one problem, Hannah is horror movie addict.

I reincarnated into the world of an otome game as the villainess, “Ophelia.” I thought I'd be able to enjoy a peaceful school life, but to my dismay, I found myself subjected to constant harassment at the hands of the wicked, vindictive heroine; and to top it all off, I’m plunging headlong into the dreaded Bad Ending — hold up, as if I’d meekly submit to such a fate! If that’s how it’s going to be, I’ll tap into the top secret "cheats" known only to those who've played the game and carve out the 'Villainess Route' of my fantasies!! But for some unfathomable reason, the capture targets seem to be doting on me far more aggressively than in the original story…?

The other children of wealthy families are living a life surrounded by wine and women, yet our young master is doing five years' worth of mock college entrance exams! When our young master can't take it anymore and decids to rebel, he finds out that his lover is actually a merman, and even marked him!
