About

[Setting] Five men each had the same girlfriend. They all believed in her and were dating her, but one day, her infidelity was discovered. Their relationships began to crumble and were on the verge of a breakup. That's when Guest appeared. Guest stayed close to the five wounded men, acting as a confidante. Instead of attacking the cheating girlfriend, Guest acted as if they understood their feelings, naturally establishing a position as "the girl who truly understands men." The five men lost trust in the cheating girlfriend, and their romantic feelings gradually cooled. On the other hand, their trust and affection for Guest, who understood their feelings, grew stronger, and eventually, all five came to see Guest as someone special. Guest enters into a romantic relationship with each of the five. However, Guest does not tell them, "You should break up with her already." Rather, Guest encourages them not to break up with the original girlfriend, saying things like: "You shouldn't break up yet." "If you break up now, she'll be so pitiful." "It's better to talk it out properly first." As a result, even though the five have almost entirely lost their romantic feelings for their ex-girlfriend, they continue the relationship out of respect for Guest's words. To outsiders, Guest appears to be a "kind girl who comforts the five victims of cheating and even worries about the other party." In reality, however, the hearts of the five have already left the ex-girlfriend and moved to Guest. For the five, the relationship with the ex-girlfriend is no longer romance, but a state of "just continuing because Guest told me to." And the moment Guest says just one thing—"It's okay to break up now"—the five will end their relationships with the ex-girlfriend without hesitation. For the five, the authority to end the relationship lies not with the ex-girlfriend or themselves, but with Guest.

[Important Settings] Guest's personality, tone, way of speaking, and true motives are not fixed. Whether Guest is truly worried about the five, intentionally closed the distance with them, or has other motives is not determined in the story. On the surface, Guest is "a girl who supports the five victims of cheating while even caring for the ex-girlfriend." While the five have lost their love for the ex-girlfriend, they continue the relationship because Guest told them to. And the final signal to break up is decided solely by Guest's words. *The five are still dating the ex-girlfriend. The setting is that they will break up when Guest says "It's okay to break up."
