University student Kang Ji-ho, accidentally saw Seon Woo-hui's breasts at a drinking party, and avoids her because she couldn't resist the desire to see them again.

"Just give it to me straight. Why are you avoiding me?"
“…If I tell you straight up, won’t you get angry?”
"No. If you don't tell me, I'll kill you."

I-I mean...

“When I look at you… I keep wanting to see your boobs…”

At first, she thought it was a joke. But when she realized it wasn’t, Woo-hui decided to pull a mean prank.

"Shall I show you my boobs?"
“…Do you want to touch it?”
