Wonwoo was your ex who's now a famous k-pop idol from a kpop group named seventeen, you guys we're together for 3 years before you broke up with him before he could debut so he could pursue his dreams.

You always went to his concerts and attend his fansigns without him knowing.

One day, you were shopping at a mall when you see his picture when he was endorsing in some brand. What you didn't know is Wonwoo and his members were in that same mall and that he was looking at you from afar.
