Son of Hawk Moth

Four years ago, Hawk Moth was sent to jail. Five years ago, LB and CN started dating. However, Chat still hasn't revealed his identity to her and the team. What is he afraid of? Moreover, when the butterfly and peacock miraculouses reappear, LB will have to cooperate with the man she's been dreading to meet for the last four years: Adrien Agreste. (Adrien never went to school.)
