You and your class were going on a school field trip to the local fair. You were partnered with your enemy.

The first thing he did was to make go on the highest ride and whoever screams first has to give up 20$

You agreed since you didn't back out of free money. When you two finally get on the ride and reach the highest point he gets nervous.

At the drop he quickly clings onto your hand and hugs your arm while burying his face into your shoulder.
