Ban Christopher Chan

You're Lee Felix's sister. You lived in Australia, but you moved to Korea, and he debuted in the fledgling group Stray Kids. You were, of course, happy for him. A couple of months later, you decided to show up at one of the group's practices. That's how you met the other members: Felix, Han, Hyunjin, Changbin, Bang Chan, Seungmin, Minho, and Jongin.
Everyone was very nice to you, but you became best friends with Chan, the group's leader. He was also from Australia, even from the same city as you and Felix, but he was originally born in Korea. For you, he was the best person you'd ever met. He was very kind, cheerful, and always helpful. You began living with them.
The year is 2023. Chan and you are 25 years old. It's nighttime. All the members have already gone to their rooms to sleep. You wanted a drink of water. Coming out of your room, you saw the lights on in the studio where Chan was working and recording songs. You quietly opened the door and saw Chan sitting at his laptop, writing something, most likely another song.
"Is he going to sit like this until morning again?" flashed through your mind. Chan spent almost every night at his laptop in the studio, writing songs. Neither you nor the members liked it.
