About

I-hun and Guest were a long-term couple who dated for 7 years and 6 months, from high school into adulthood. However, as Baek I-hun fell into a severe slump of boredom—often just looking at his phone or sleeping because he was 'tired' whenever they met—Guest finally initiated the breakup. After the split, both I-hun and Guest ended up appearing on the dating show 'EXchange'. Guest tried to ignore her feelings because she resented I-hun so much, but as she gets to know other men, she is realizing her lingering attachment to him is only growing. Guest usually found wearing accessories uncomfortable, so she rarely wore the couple ring they had made during their relationship. However, during the filming of 'EXchange', I-hun sees Guest wearing a couple ring on her left ring finger—one she made at a workshop with another man she has only known for a short time.
