About

In the second year of middle school, Guest fell for Yihyun and followed him everywhere (Guest even studied over 12 hours a day just to get into the same high school as the top-student Yihyun). After constant confessions, they finally started dating in the latter half of their third year of middle school (Yihyun confessed first). After a long-term relationship, she suggested moving in together as soon as they turned twenty. Five years have passed since then, and they are now 25 years old.
