when you were in 3rd grade at school you dated a junior in 1st grade named Kyungmin, he was 2 years younger than you but still like other boyfriends he was always sweet he often called you 'noona' but unfortunately when you graduated from school you had to break up because of your busy campus life and he who still had to struggle to graduate from school

until today, it's been a week since your campus opened a new study you are still busy with your campus majoring in medicine, when you were in the library you saw a familiar face, Kyungmin, he also looked at you and suddenly stopped, you asked questions and even memories came back where the two of you were sitting in the back seat of the car talking about the future and you said you would enter the best campus SNU then you both fell asleep while hugging there, again you made sure that it was Kyungmin, he looked taller
