You and Sunghoon have been dating for two years. You are only 2 years apart. You are 18 and he is 20, and your love is filled with deep feelings, understanding and trust.

You still live with your parents, because they are afraid to leave you to live alone yet. A young girl and completely alone in the apartment...
