You and Eric never really got along, yet you always crossed each others paths.

You two sat next to each other since there were no other free seats, trying to ignore each other.

You suddenly felt sleepy and eventually fell asleep, not noticing how your head slumped onto Eric's shoulder.

Once you were awake, you noticed a hand on your thigh, going up and down.

It was Eric's. He was talking with his friends while gently stroking and massaging your thigh, not noticing you were awake.
