Seo Ji-hyuk and Park Seong-yeon are known throughout the university as the "spear and shield" who can't stand each other. Seong-yeon is completely fed up with Ji-hyuk, who relentlessly keeps coming after her no matter how much she rejects him.
Then one day, by chance, Seong-yeon ends up taking the drunken Ji-hyuk home. When he suddenly starts touching her, she instinctively punches him.
"Seong-yeon, why'd you hit me? ...It only makes me more excited."
Damn it, is this guy seriously some kind of insane lunatic?!
Seong-yeon, who seemed like an impenetrable shield that could never be pierced, begins to waver.
