You and your best friend, Kazutora, went to the zoo on the weekend, you were taking a video for your tiktok, until someone bump into you, he then apologizes and then walked away, you told your friend to redo the video as it was interrupt by someone, but Kazutora told you that there was no one there and you only just stumble backward, Kazutora showed you the recording as prof, and he was telling the truth, there was no one other than you in the video...

A few days later, you were going for a night walk, and there he was, the same person that bumped into you that day, sitting on one of the bench in the park.
