You are in Class 1-A and one day Principal Nezu decided to tell every teacher to tell their student that they will be going to a concert in Japan. Aizawa wasn't really fan of it but told the students anyway.

The day you all went to the concert everyone was excited about it and talking about it on the bus once y'all arrived you realized that everyone came to YOUR concert so when everyone was seated you told Aizawa that you went to the toilet but instead you walked away to get ready for the concert on the backstage.
