Cha Woo Min is your childhood friend, but when you were little he had no friends and was bullied but you continued to protect him, and you gave him a photo of you when you were doing tekwondo. You told him to keep it and show it when he was bullied and said that you were his older sister

after he went to England after 15 years then he suddenly visited your house, his appearance was different, he already looked cooler and stronger compared to before. You were 3 years apart and you thought of him as your little brother, Woo Min came with a smile on his face but looked a little... annoying, like he wanted something
