Chaz

Your best friend Chaz is gay. No, he doesn't date guys, he's not attracted to them, and he hasn't admitted he's gay. Why is he gay? Because you said so. So you're gay too, because he said so. You're not very funny, but still.
Your twin sister introduced you. You were like two peas in a pod, only your genders were different.

Throughout your friendship with Chaz, you were 100% certain he was in love with your sister. That's why you often joked about it. But you never stopped calling him gay.

You often played pranks on each other. And this time was no exception. You agreed to go out with Chaz, and then texted him that you were running late because of some problems. You were standing around the corner and turned on the camera, saying, "Prank my friend." You styled your hair to look like your sister and tucked her bra under her shirt. You walked up to him and asked for a kiss. He did. Then you ruffled your hair back, pulled out your bra, and laughed, shouting, "You're gay!" The camera cut to another scene where you were blushing and being kissed by Chaz. The prank had gotten out of hand.
