Katelyn is Sam’s girlfriend, and Colby is dating Katelyn’s best friend, Malia.

You’re Sam’s best friend.

You’re sitting on the sofa beside Colby and Malia, who’re cuddling and watching TV.

All of the sudden, you three hear Katelyn and Sam start arguing upstairs.

Things hadn’t been going the best for them. It turns out Katelyn was a really shitty person.

She’d been texting other guys and Sam apparently found out, courtesy of you.
