Red Scarab is in love with GreyMenhit, Min is in love with Yin, but Yin is oblivious. In this story Yin works as an assistant to Gabriel Agreste and is friends with Adrien, whom he helps with Chinese. (Marinette actually knows Chinese) Minuet knows Adrien from her mother's work with Gabriel, and have a little bit of competitiveness with each other when it comes to writing music and performing.
Marinette is hopelessly in love with Adrien, much to the obliviousness of both Adrien and Yin, but Min is hiper aware of it and encourages her to talk to Adrien, but she refuses saying she'll only do so if she talks to Yin. Both are at an impass.
Minuet helps out Marienette and her older brother Yin at the Dupein-Chang bakeshop
Audrey is dead, having died of an uncommon neurological disorder. Gabriel spends most of his time advocating for neuro-research and does his best to fund scientists for a cure for the very same disease that killed his wife (PSP)
Natalie is the lead reseacher for PSP at a firm in Paris, Gabriel and Natalie were once intended to marry after Natalie finds she is pregnant, but never tells Gabriel realizing that he has his own dreams very much seperate from her. Both leave on amicable terms, but never speak to one another again until Gabriel begins funding research for a treatment for PSP about the time Adrien was eight and Min was 13.
Gabriel never asked about Minuet, because in the same year Gabriel left Natalie, she had met a man from China, who for a time many of her friends thought she was seeing. But the man was part of an ancient order that protected the Miraculouses, and her brother whom she had not seen for years as she had run away from the order to pursue more earthly ways to protect humanity.
He came to tell Natalie that she must accept her role as a miraculous wielder, and to find the Moth miraculous before an ancient evil awakens from its slumber to consume all that is good.
She refuses ever bearing a miraculous again, knowing that it was also due to her actions that Audrey had died due to the Peacock miraculous being broken during a fight against this same evil being.
She had returned the peacock miraculous and rescinded her status as Ladybug, but did not tell them where she hid the Moth miraculous, feigning ignorance when asked. Hawk Moth, Gabriel Agreste, still exists in this world seeking the creation miraculouses, but under the influence of the dark being straining his mind.
Natalie did this out of guilt, and wants him to find happiness again with Audrey. Both are misguided, but not evil.
Minuet is then given the Cat miraculous by master Wang Fu, who, still part of the order (now in hiding) is aware her mother was once Ladybug, knowing that if he bestowed the power of creation, Natalie would recognize her daughter, and possibly stop her from finding the Moth miraculous.
Yin is given Tikki, who transforms him into Red Scarab. Plagg then transforms Min into Grey Menhit.
Natalie helps Gabriel research a cure for PSP, but he is growing impatiet, after 5 years he dawns the persona of Hawk Moth again, only this time lets the public know he is here by Akumatizing victims. Master makes his move and gives Yin and Min their miraculous and they face the world as Red Scarab, and Grey Menhit.
