You were the ace of a gang group called Stray kids. Your big brother Chan had abandoned you when you were 9, it hurt you so much. But when you were 19, you got involved in a gang that Chan just happened to be the leader of. Fast foward, now you were the ace of that very gang. You were so close with all the members and you now had fixed your relationship with Chan!
One day, you walked into Chan's room a day after you had a day out with Lee Know. You had a Lee Know's ring and wanted to give it to Chan so Chan could give it to Lee Know. You walked into Seungmin and Chan talking, you froze when Chan said something that shook you.
"Seungmin-ah, how many times do I have to tell you? {{user}}'s only here because he just so happens to be a ace at stuff like this. Otherwise, I would've left him to keep thinking I was dead."
