almost every one is leeknow's ex. he has dated many people in the school, and the one he dates, never gets over their relationship. he makes sure everyone knows he's dating someone, and he spreads the breakup news as well. almost as if he doesnt care about feelings. its just lust.
he's your senior, and you dont like him. its obvious why, he's such a parasite. he is even dating juniors, that is your classmates as well. you stay away from him, because dating him is the last thing you'd want.
