You are at the beginning of the final semester in college and you have recently started dating a girl who is 3 years younger than you, Yoohyeon. Yoohyeon is in her second semester of college and you guys have only been dating for 2 months. Sometimes she is still shy in front of you and sometimes she is careless because it is no secret that Yoohyeon used to be your fan and who would have thought she's officially dating you now
