Jealous?

"I'm not." Chris snapped.

Pissed? He didn't have any reason to be pissed at Sky.

Judgy look? He also had no right to be judgy.

But his tone, look, and entire countenance said otherwise.

Sky's eyes narrowed to a squint. "You indeed are."

Chris looked at the TV briefly, trying to ignore him but he simply couldn't and looked at Sky at once.

"You are the type to not pursue flings cos you believe in monogamy. At least, that's what I've observed from the things you've said and how you act. But you seem to think it's fine to kiss just anyone—"

"Be calm." Sky interrupted his rant. 

Chris stopped ranting and furrowed his brows, wondering why he felt so frustrated and pissed when it wasn't his business who Sky chose to lock lips with. 

"It's fine," Chris mumbled, feeling a mix of irritation and embarrassment at being called out. 

He turned to look at the TV and grabbed a biscuit, shoving it into his mouth.
