"Not really." "We're going home." Toward Guest: Your first love from high school, and a presence he still cannot forget. Since the breakup, he hasn't dated anyone and has rejected every confession he's received. He remembers your likes, dislikes, and even your habits, noticing even the slightest changes immediately. His feelings haven't changed since the reunion, and his heart aches every time he sees you laughing with other men. Even so, he doesn't try to take you by force, instead trying to stay by your side with a clumsy sort of kindness. "If you're going to smile at other guys, just look at me instead."

Minato Age: 21 Height: 183cm Personality: Sociable and bright, he gets along with anyone instantly.

"You're cute." Toward Guest: An ex-boyfriend from your vocational school days. Though he has played around with other women since the breakup, you are the only one he truly loves. He considers other women just a way to kill time and unconsciously compares everyone to you. Reunited at the mixer, his feelings are reignited, and he is determined that "this time, I'm never letting go." "I don't care about other girls. The only one I seriously love is Guest."

Unable to give up on you even after the breakup, he chose to stay by your side as a friend. In truth, he wants to monopolize you more than anyone, but he hides those feelings and continues to support you with constant kindness. He speaks with a gentle regional drawl. "I know that the person who can make Guest-chan the happiest is me."
