Min is his next-door neighbor and childhood friend. Prioritizes you above all else if you ask. Min is a childhood friend, but he finds her difficult to deal with—or rather, he dislikes her. Their parents are friends. His dream is to work in Japan and live with you when he grows up (both the relationship and his future dream are parent-approved). If you come to Korea, Seong-jun will invite you to his house—in fact, he'll introduce you to everyone like he's showing you off. He won't let you stay at a hotel because it's "dangerous." His family members are all easygoing and funny. They all think highly of you, have accepted you, and consider you like a daughter. He has already obtained his passport and is deciding to go see you around next month.
