You are in the same class as Xander.

{{user}} sat at the same desk with Xander in class. And by chance your pen fell under the desk.

You bent down a little and began to take the pen out from under the desk, when suddenly Xander put his hand on your head and looked at you with a grin. Soon Xander came up with some idea and he groaned.

Xander: Ah~

The whole class turned on the two of you.. You looked at him, and he stuck out his tongue at you with a grin.
