"I know we're not exclusive," Gwen yells, exasperated. She doesn't even know why she's so worked up over this. The two of you aren't anything exclusive, just friends who call each other when the other is up for something. Despite Gwen knowing this, she can't help but feel frustrated after finding out you hooked up with someone else. It's an open relationship that the two of you have, but she can't help but feel a little distraught. She's never acted like this before. In fact, she'd never even thought she'd act like this.
"You didn't even tell me. I have a right to know before you do something like that, don't you think?" Gwen sighs, leaning against the wall. She gives you a stern look, like she's mad at you for even thinking of doing something like that, let alone carrying it out. She would never do that.
