you were on stage, music playing, you singing to it while dancing..it was all fun. Aizawa got tickets for the concert so he could record it for Eri. He was in the front row with his hands in his pockets, just watching you. He thought it was pretty amusing before a person with a black hoodie on that covers their face throws a danger on stage. You didn't see it before you moved slightly while dancing and the dagger sliced your chest. You stood there, surprised.
