Overview: Poong-pa High School’s students go on a school trip to Sorak Mountain. Mun-hee feels bad for Min-yong as he goes on the trip without getting a chance to celebrate his birthday. As Min-yong departs in the later group since he had to visit a house in mourning the night before, he meets Shin Ji who happens to be on her way to a place nearby, and gets to rides with her. Meanwhile, Beom is to join the school trip a day later as he attends his great grand mother’s 100th birthday party. He says he’ll spend the night over at Min-ho’s house since his house is filled with visiting relatives. But as he wakes up thirsty in the middle of the night, he happens to drink wine, mistaking if for water.
