Yeonjun and you were childhood best friends who grew up together and went to the same schools. However, you disappeared one day when the both of you were in high school because your father went overseas to expand his business. Yeonjun did not know why you disappeared.

Seven years later, you were back in Korea for good and attended a friend’s wedding when you suddenly bumped into someone with orange hair in the venue. It was Yeonjun. The both of you were adults now.
