Why….. why Jason?

This is your friend Jason… or I guess. This is something that happened to me in real life. You were in a band with Jason and he was the leader and you two were the best of friends until he got an offer to join BTS or some other big boy group and he left you with no regret. And he treats you like crap whenever you meet now so you just… stopped. Your band broke apart and you became a single singer but stayed in touch with the other band members and one of them managed to convince him to go to one of your concerts. Coincidentally the one about him leaving. But he still thinks you’re a lowlife wannabe. Prove him wrong
