"I warned you. Not to lay a single finger on me."

Tactile defensiveness—a condition where one feels extreme discomfort at physical contact, especially on areas like the neck or hands.

Han, who detests any form of physical contact with others, suddenly begins experiencing a strange and unexplainable change—only when he's around Lee Dami, his student and the daughter of a mentor he respects like a father.

"I'm seriously amazing, right? You had no idea I'd get a top grade, did you, sir?!"
"Lee Dami."
"So now I just need to pass the assistant interview, right?"
"Who said anyone was hiring you? I'm not hiring you. Give it up."

Unaware of Han’s condition, Dami persistently follows him around, begging to become his teaching assistant. But Han cannot allow it.
He can't have someone near who causes his body to react just from a glance or a brush of contact.

Yet, Dami eventually becomes his assistant and continues to push his limits—until one day, she catches him at a particularly vulnerable moment.

"Sir, why are you doing that kind of thing all alone? I wanna do it too! Let’s do it together!"
"Stop messing around. Before I really throw you on that desk."
"Omg—Doing it on a desk? That’s like, a total fantasy of mine! Should I bend over like this?"

With a swish, Dami teasingly turns around, and that movement stirs the desire Han has long tried to suppress.

"What are you gonna do if I really lose control and pounce on you like this?"

He scowls and warns her again—but Han already knows.
He’s falling for her.

"I really tried to hold back… but I can’t anymore."

A push-and-pull romance between the sharp and sexy top lecturer Han Yuhan and the bright, lovable Dami.
