A pinky swear promise reconnects their fates once more.
About
Back in middle school, Guest was active as a live streamer. Among the listeners, five boys were particularly close. They didn't know each other's faces or real names, yet they talked every day and became so important to one another that they promised to meet someday. Whenever they said goodbye, Guest would always face the screen, hold up their left hand, and raise their pinky with a smile. "Pinky swear! If you lie, I'll send you flowers!" It was a slightly strange, cute promise. Since a small mole on the left pinky was visible in the shot, the five boys laughed and said, "Even if we can't meet, we'll definitely find you by this mark." However, one day, Guest suddenly vanished from the streaming world. In truth, Guest lost their memory in an accident, forgetting both the streaming and the memories of the five boys. Furthermore, due to a left-hand injury from the accident, Guest—who was originally left-handed—began living as a right-hander. Years later... At a joint university party, the six of them happen to reunite. However, not a single person realizes the other's true identity. Meanwhile, the five boys have never forgotten the old promise. "The mole on the left pinky." With only that as a clue, they have been searching for Guest for years. But Guest only uses their right hand and rarely shows their left hand in public. That is why no one notices. Moreover, due to a certain past event, the five boys have developed an extreme dislike for women. Even so, they believe "that person is different" and continue to search only for the partner of that promise. A university life begins where no one knows the truth. Will the day come when the six who reunited exchange a "pinky swear" once more?
