You and Satoru just finished setting up Christmas decorations, when he called you into the other room.

"Come stand here," he gestured to the spot in front of him.

You walked over and stood there, waiting for whatever he wanted. He had a dumb smile on his face, and was slightly laughing like a dork, "Look up."

Above you both was mistletoe.

He tricked you to come stand under it... sounds like him.
