Usami is approached by her daughter, sweating like mad, asking her mom to please help her with something; a furious Usagi then tells her husband she and Toki are leaving for a while, they need to take care of something. Both of them go towards a fat guy who threatens Usami and Toki to spread all the photos Toki and fuck buddies shared on adult socials to Toki's school, that sure is to make Toki's school life a living hell and maybe grounds for expulsion.
Usami then asks what the stalker wants to keep him quiet, he then reveals Usagi was the goal all along, he was a devoted fan of a famous cosplayer Usagi-chan for many years but one day she just stopped posting, then it became his mission in life to find out her real identity and by her daughter Toki being absolutely careless with allowing her sexual escapades to be posted online the stalker found a perfect opportunity to coerce Usami, that is Usagi-chan, to do what he wants which is to resume her life as the cosplayer Usagi-chan but only for him, at his home, for a little while.
Usami goes back home, tells her husband what happened and scolds Toki for being a dumb slut; her husband worries about the arrangement and what the stalker may do but he kinda likes the idea of Usami becoming Usagi-chan again, Usami shushes him by saying Usagi-chan is being coerced into coming back, is that fine? Still, she tries to calm him down and say everything is ok.
At the stalker's home Usami does his bidding, cosplaying to his heart's desire, but that's when he pushes the evenlope, wanting Usagi-chan to serve him sexually, naturally Usami protests but the stalker pulls another card up his sleeve, he actually knows Usami never quite left the online life, she just changed her game, Usami became a Urakajoshi, doing erotic anonymous photos but since he is a devoted stalker he could tell it was her all along, he was hurt his favorite idol dared to hide from him with a secret persona, so she is pressured into doing his biding otherwise he will reveal the real identity of Usapai.
Usami doesn't want her husband to find out she is doing erotic Urakajoshi in secret due his inability to give her some good sex after his hardous mangaka life destroyed his libido and vigor.

Stalker didn't need to threaten Toki with those pictures, look at how insane they are, everyone would find about them in due time, holy shit, you can't even pretend to be embarrassed anymore if you entertain doing that level of sex.
