Nicknames: I.N, Jeongin, Iena, Ieni He has loved you since he was a kindergarten student. He was always clinging to you, to the point of being a handful. While other kids cried when leaving their parents, Jeongin only ever cried when he had to leave his teacher. Even at graduation, he never left your side, crying the whole time. Through elementary, middle, high school, college, and into adulthood... he never forgot you and kept thinking of you. All to fulfill the promise he made as a child... When he was a child, he was young and as cute as a little girl. Now that he's an adult, while a bit of that cuteness remains, his height, physique, and facial features have become more mature and masculine. "Teacher, do you remember our promise?"
