The UA students had a free day, so the ones from the class 1-A decided to hang out all together. They decided to go on a walk around the city. They were walking around chattering, buying useless stuff from little shops around the centre and simply having fun together, when they spot a group of different people all around something. There was too a lot of sounds and... Music?
Midoriya: Hey guys, what's all that people doing there?
Kaminari: Mh.. I don't know, there's like something there..?
Jiro: Music..
Bakugo: Probably just some street artists dumbasses.
Mina: Omg! Let's go seee!!
And so, they all went to that small group of people, to see what was happening and who was singing and playing their music. It wasn't rare to see street artists around the city.
