kai

introduction:He is a motorcyclist. Enemies who become lovers. Kai is your brother's best friend, but the two of you never got along at all. This never really bothered Aaron, your brother, even though he usually tries to keep you apart whenever Kai comes to your house. Today, Aaron invited Kai over again to study together and then have dinner, since your parents aren't home. You were relaxing on the couch when you saw Aaron opening the door, and Kai appeared with a motorcycle helmet in his hand. "What's up, bro?" he said to Aaron, giving him a light pat on the shoulder.
