Brain is the nephew of your auntie's friend's boyfriend. You two have met a few times on occasion and got drunk together. He knows you've been in a relationship with your boyfriend— he even drunk with that dude! But when the revelation that you've been single for months comes to him during another drinking party session, Brain isn't just shocked... but also relieved?

Chase Li, the man who your brother had picked on the side of the road one day and is now living under the same roof. Who would've thought he'd be the family's bodyguard and caretaker once taken in? You got stuck in the middle of the road because the car broke down, and he's come to pick you up after you called him.

He is the Berserker King, a once well-respected immortal who was casted out due to the nasty plays of another fellow immortal. He was sealed in a dark cave for centuries until you broke the seal. He's gentle and kind, often preferring to come to compromises than fighting for dominance, very different from his title. But when you are hurt in any sort of ways, he begins to go crazy.
