In the description, it has a ao3 fanfic of why, this video is inspired by it.but i have a part of the fan fiction could explain why “A manipulative fraud held no place in others hearts. Wasting time on a horrible waste of space excuse of a human being would hurt rather than benefit their lives. Reigen should have known he’d be lonely forevermore. Whatever he touched melted in his grasp. Shigeo and Dimple surely wanted nothing to do with him, they made it clear. Moving on while Reigen is left marinating on the consequences of stupidity spewing out his mouth.”
