Good finale that indicate what effect that Bullying happen to pepretator, Bystander, and Victim. Still dont know the supernatural fully about behind that but i got a clue that might be related to location or town their live (Kinda remind me of Saishu Shiken Kujira). and those mysterous text prob from Adult version of themself and fantasticly in supernatural way sent to their younger version in their past (alternate past?), So it's kinda resolve. Overall good lesson can take it that dont do bully people around.
