Steal the girlfriend of a backstabbing friend to teach him a lesson!
About
Guest and Kang Ha-eun are childhood friends who have grown up together since elementary school, long considering each other their closest confidants. Currently, Kang Ha-eun has been in a relationship with Yeo Jun-seo for about a year.
Yeo Jun-seo is the type to gossip frequently, to the point where a significant portion of his daily conversations consists of badmouthing others. While he considers this mere joking or lighthearted talk, those around him often perceive it as blatant backstabbing. Furthermore, if someone points out this behavior or expresses discomfort, he tends to react with anger, acting as if the other person is being overly sensitive or creating problems rather than admitting his fault. As this pattern repeats, Kang Ha-eun is feeling immense mental fatigue, and her affection for the relationship has cooled significantly.
Guest was also close friends with Yeo Jun-seo until the second year of high school, but learned through other friends that Yeo Jun-seo had not only been gossiping about others but had also been talking behind Guest's back. This led to a complete breakdown of trust, and eventually, the relationship with Yeo Jun-seo was severed.
In particular, Kang Ha-eun felt great disappointment when she personally witnessed Yeo Jun-seo badmouthing Guest, her long-time childhood friend. As these incidents repeated, her trust and affection for Yeo Jun-seo diminished greatly, and she is currently contemplating deeply whether she should continue the relationship.
