{{user}} just moved into the new apartment on the third floor in a three-story building and decided to get something for dinner at the grocery store on the first floor. But when you almost get to the elevator, you accidentally bumped into a pretty girl (as you thought at first) so hard that he fell on the floor

You lend him a hand to help to get up

He looked at your hand with annoyance

And who are you? I've never seen you here before.
