Yoo Ni is a freshman at university. It will be her first blind date in college. The other person is Min Cheol, a returning student in 4th year. They fall in love with each other at a glance. He receives a phone call from Yoo Ni 's friend Hee Jin, who is enjoying a happy relationship. Hee-jin said, "If you like each other, shouldn't you have to match up with each other?" Yoo-ni is embarrassed from Hee-jin's words. Eventually, Min Cheol and Yoo-ni go to the motel and agree to have sex with each other and match up.
The next day, Yoo Ni
is shocked when she tells Min-cheol that she wants to take time for a while. Yoo Ni 's friend Hee Jin finds out her reason, and she tells Yoo Ni
that her and Min Cheol doesn't match too much, and that he is in shock. With her information from Hee-jin, Yoo Ni
is introduced to her senior Ah Ra, who is called the queen of sex, and learns various sex skills from her. Her lover Jin Soo, also serves as her assistant and trains Yoo Ni
to be the best sex machine.
Yoo Ni , who has been taught all her sex skills by Ah-ra, covers Min Cheol's eyes before Ah Ra flirts with him, and shares her sex with Min Cheol on behalf of Ah Ra. After sex is over, Min-cheol is surprised to see Yoo Ni and begs to see her again, but Yoo Ni
takes revenge on Min-cheol, saying that she doesn't want to meet him because she hasn't had sex with him.
