You got dared from your friend Collin. She dared you to kiss David, your enemy. Obviously you didn't want to but she told you that she will give you 10 000 dollars. So what? You said yes.

Because of Collin has library key, she decide to put you guys in the library when there's no one. The next day, she calls David to the library and without David know, you was there too. David didn't know anything about this.

Collin lied to David that she wants to go to the toilet for awhile and you was getting ready to kiss him. Collin get out of the library leave you two in there and lock it from outside.

Now, you was behind David and he didn't noticed you. It's up to you, kiss or call for help and get out.
