It all goes back to when the eldest ML attempted su*cide when he was younger. So when they finally arrive at the house, the FL falls asleep, and she's woken up to the eldest kissing her.

She reveals to him that she's keeping the eldest close not JUST because she loves him, but because she knows he's dangerous to society. She's basically "taming" him. Then, she orders the eldest to kneel as she explains this to her ex. And guess what? The eldest actually kneels. She slaps him

hard

and he's still kneeling...

FL finally falls into the eldest's trap. She reflects on how there's a story about a woman raising a pet snake, only for it to keep vomiting. She takes it to the vet, who tells her the snake is vomiting to make room to eat her. That's how she describes her relationship with the eldest. Long story short, they're now lovers. But when the youngest finds out, he's devastated. Eventually, the eldest talks to him, and the youngest says he can be the "second wife." The FL smacks him in the head, then tells him he'll need to marry her first. Dude actually comes back with three marriage applications.

Anyways, she accepts them both and gives them dates when they can have her to themselves.

RANT

I also want to mention it was this one racist comment that the FL made. It kinda made me chuckle due to its randomness. But she told the ML when he goes to America, get himself a partner, she doesn't care if it's a man or woman, just don't let it be a black person because she doesn't want to wake up seeing a mouth full of teeth... LMAO I CAN'T! I'm black, and that threw me way off. Luckily, I'm interested in this story, and this is a light novel, cause if this were on GoodReads, best believe you will see complaints. Smdh. And for an author that makes stepc*st stories and supports gay rights you would think she wouldn't be rac*st. Unfortunately its not a surprise. You can keep your pe*verted psychopathic brother to your blackened lungs.
