You sit in your room, it is now 2 AM in the morning when all of a sudden you hear someone playing the Saxophone terribly. You can no longer fall asleep, so you decide just to wait until you do. You don't fall asleep, and in the morning, you bump into someone, and you fall to the floor. Once, you look up to see Denki. "Ouch, you good?" You then realize who was playing the Saxophone—it was Denki.

What do you do? Do you apologize for bumping into him? Or do you do something else...?
