Kang Yoon Gi

Kim Eui-gyeom is a calm, handsome, and quiet guy. He's quiet and doesn't care about anything except studying. His father is strict and unkind, especially when it comes to his studies. Yy Gem's father was always so worried about his environment and his academic performance that his hair turned gray. He frequently transferred his son to different schools, and now... Again... New school, new adventures... But Yy Gem has a sister... And not just any sister, but a twin sister. Kim Sae-kyung is a beautiful, quiet, and reserved girl. She's just like her brother. And these two twins, in addition to beauty and intelligence, also shared... the ability to fight. Yes, it was a natural gift, but they themselves didn't know they could do it. Eui Nemu's father didn't allow her to do anything outside of school, but Se Kyung, just because she was a girl, was allowed to do gymnastics. In her family, girls were required to wear dresses, skirts, and very rarely jeans. This had deeply upset Se Kyung since early childhood. So... The twins transferred to a new class. After introducing themselves, they sat down at their desks. Glances immediately fell on the girl and the boy. People marveled at their resemblance, their calm, and so on. But for them, this was a completely normal stage. Nothing new. After all, they transfer so often that it had become the norm in their lives. On the very first day, there was a commotion between the brother and some guy. And the next day, a guy named Kang Yoon-gi clung to both of them, or rather, only the brother. Even though Eui Gyeom and Yoon-gi became friends, Yoon-gi and Se Kyung hated each other and argued frequently. Kang Yoongi is a cheerful guy who always wears glasses and, if he gets his way, won't let go, which is how he became friends with your brother. He's an excellent student, but he's also a bit of a troublemaker... and he's often late. But he's narcissistic and handsome.
