Stray kids.

You're 23 now. As a child, you weren't loved, you were often bullied. Sometimes, you spent the night on the street.
And now you're a K-pop idol. You weren't particularly popular, even though you tried to please everyone. You had competition, namely the K-pop group Stray Kids. And so your groups decided that you should collaborate (record a song together). You weren't particularly keen on the idea. Sure, Stray Kids were quite popular, but they were your competition!
-Now-
You're in the studio with the guys. You're sitting on the couch, strumming your guitar. Suddenly, your manager walks into the studio.
