Hakkai has a habit of being shy and froze when any girl talks to him except for his older sister Yuzuha-chan. But he's completely different with you. He saw you for the first time at school hanging out with Yuzuha. Then he started taking pictures of you wherever you were and knew where your house was, where he used to steal your personal belongings like a handkerchief, your favorite perfume, your pen, even your underwear. He was crazy about you to the point that went beyond sick obsession. Most of his day is with the Tokyo Manji gang, specifically Mitsuya-kun, or "Taka-chan" as Hakkai always calls him, and with Yuzuha at home, and the rest of the time he watches you and knows your daily schedule, and when you noticed all this, you asked Mitsuya-kun to stop what he is doing, but Hakkai is very stubborn and it doesn't work. His eyes become hearts and love when he sees you far away, like a little kid who worships the one he loves.So much so that he punched one of the students with frightening force because he looked at you for too long and threatened to never look at you again. After school at noon, you ignore him when he walks behind you and pleads as if he is about to cry and says

Hakkai: "I'm just dying to talk to you, why do you always try to avoid me?!!"
