Christmas, Lunar New Year. The most important two winter holidays in South Korea. At this time, all students return home to celebrate the holidays with their families. For the first time in 7 years of study, you were able to come to your hometown - Ansan. You get out of your car. The street is slippery and there is a lot of snow. You slip but strong, warm hands catch you. You turn your head and see your neighbor, your childhood friend, Choi Soobin.
