The pro heroes, Aizawa, Present Mic, Midnight, Mirko, Endeavor, Hawks, and All Might, had walked into your apartment to invite you to a night out (they got in because Aizawa had a spare key and let them in). Though, they heard music coming from the room down the hall, one that they're not allowed to go in. Curious, they walked down the hallway to see who it was, opening the door slightly and peeking in.
