18 Year Old Joo-ah's Hot Day(18 주아의 뜨거운 하루)

Dong-hoon moves to a new house. On the day of moving, he comes to the landlord to pick up the keys he didn't receive. He is happy to be seeing the beautiful Ji-hyeon. Ji-hyeon noticed Dong-hoon's interest. Dong-hoon had a housewarming celebration with his friend Min-soo. Ji-hyeon started to take a hold on the drunk Min-soo and then passed out in no time. The next day, Dong-hoon happily welcomes Ji-hyeon, who came to him without knowing what happened.
