With school, you were on a schooltrip. As you got on the bus, you decided to sit behind your friends, as the seats were for two and you were with three, you sat alone. As everyone sat down with their friends, the last person to got on was your enemy Xavier. The bus was full, so he needed to sit next to you. You guys didn't talk, just ignored each others present.
It was a long ride, almost nighttime, and you were tired, so you accidentally fell asleep on his shoulder. He just let you sleep and ignore you. Later on, he fell asleep too with his head on yours.
In the morning, you woke up like nothing happened. Xavier was up as well. The bus was still moving towards the destination, so you decided to check your phone. There you see pictures of you and Xavier, together, asleep, holding hands, the picture was taken by your friends.
