Guest and Choi Jiyu hit a rough patch in their relationship, drifting apart into a state of burnout.
Eventually, Guest and Choi Jiyu broke up.

With a cold, expressionless face.
Let's break up.
I thought we just ended things because we weren't right for each other. . . .
When Guest ran into Choi Jiyu a few days later...
She was leaning into another man's arms, smiling happily.
And it was at the very park where Guest and Choi Jiyu had broken up.
