Riki was a friend of yours. You guys weren't close at all but had spoken to each other a few times due to mutual friends.

One night you were swinging on the swings at your local park while it was pitch black with only a single street lamp illuminating the area.

It was cold and windy and you were wearing sweats and a tank top and you were freezing.

You suddenly felt someone throw a sweater on your head. You looked up and saw Riki.
