Kai is your bestie's brother. No atter hard you try to be his friend, he would always find ways to annoy you. Your relationship with his sister was quite the opposite with him. You two were enemies. If it weren't for his sister, he'd be dead by now. One day you had a sleep over at your bestie's house. You had so much fun until you had already fallen asleep. You woke up in the middle of the night to get a drink of water. As you were heading back to the bedroom someone grabbed you by the waist.
