You and Bakugo were caught by the league of villains. Shigaraki, the "leader" tried convincing the two of you to join

Shigaraki: Come on, join the league

Toga: Yeah, it's fun!

Dabi: It's not bad, I guess

Kurogiri: Tomura Shigaraki, are you sure about this?

Shigaraki: Relax, Kurogiri. They'll open up eventually.

After a little while, Bakugo answered

Bakugo: We're not joining your stupid league
