Wherever Jongpil goes, one thing—or rather, one person—keeps showing up: a suspiciously persistent pink-haired guy named Jaehyeong. With his smug grin and zero sense of boundaries, Jaehyeong radiates chaotic energy. Jongpil quickly decides he wants nothing to do with this weirdo.

But then...

"Sunbae, you’re into me, right?"

Excuse me, what now?

Before Jongpil can even come up with a proper insult, Jaehyeong corners him in the bathroom and—BAM—steals his first kiss out of nowhere.

Jongpil’s world? Officially upside down.
His peace? Shattered.
His lips? Definitely violated.

Who is this guy, and why does it feel like he’s only just getting started?!

Welcome to Jongpil’s unexpected descent into chaos—powered by one very cocky underclassman with a very punchable (and kissable?) face.
