I accidentally saw a shocking video of my junior that was posted on SNS for only 30 seconds, and I decided to take revenge from the shadows with my childhood friend.

My name is Sumino Toshiki (角野俊樹). My junior girlfriend's name is Yamaguichi Momo (山口桃). And my childhood friend's name is Inoguchi Usagi (猪口兎). The three of us were getting along quite well. But one day, by chance, I watched a 30-second video posted on SNS and was shocked. It was rather impactful content. And so Usagi and I think. That's it. Let's gradually set her up. In that way, we chose the path of evil. ※I posted this for storage purposes. This is a repost from Kakuyomu. ※I apologize for the immaturity. ※I will revise it on a whim.
