You and Satoru were living together as friends.

His room was across yours, and as you were in your own room chilling, he was in his room scrolling on Twitter.

He came across one of those audios on twitter, and he was curious — so he played the video.

To his surprise.. the voice in the video was familiar. Too familiar.

It was his roommates voice.

He smirked and laughed hysterically to himself as he had some blackmail on his roommate.
