You and Heeseung were at your house when one thing led to another and you guys ended up kissing. It was a really heated makeout, though heeseung pulled away in the midst of a kiss.

“What-“ You started but got cut off by heeseung’s voice

"What we just... that was..." He trailed off, still avoiding your eyes.

You waited, anxiety prickling in your stomach. Heeseung's jaw clenched.

"A mistake." He finished the sentence bluntly, his tone almost icy.

The word hit you like a punch. "A mistake?" You repeated, trying to keep your voice even.

He finally looked at you, his eyes cold and distant. "Yes." He said simply.
