Thinking more about MayuMiko and I have some revisions.
Mikorin, trying to boast about his womanizing “prowess” starts telling Mayu how he’s already seduced every girl at his school, this ramble goes on so long that he ends up asking Mayu if he knows any cute ladies for Mikorin to work his magic on.
Mayu thinks of Mamiko, but explaining the whole situation is too much energy so he just says “sure”. Mikorin asks Mayu to describe this girl, Mayu describes her in as few words as possible-he is literally describing Mikorin to himself but Mikorin is not intersted because she seems like a “boastful and embarrassed person”.
Mikorin then asks Mayu if SHE has any friends, Mayu thinks of himself (MayuMayu), and once again decides explaining is too much work so just nods.
Nozaki’s interest is peaked and he pushes Mayu to set up Mikorin with this girl for manga material. Mikorin leaves confident in his lady skills, ready for his date. Explaining what has just happened/getting his brother to stop fixating on this date is too much work so come the day of the date, Mayu just shows up. Nozaki catches on that there is no actual girl and finds a cheap wig and quickly tosses it on Mayus head- he still wants manga material.
Mikorin shows up for the date, despite all his big talk he’s to nervous to even look this girl in the eye! But he seems to be getting along with her, she reminds him a lot of his buddy Mayu. A little too well, Mikorin realizes that this girl is way better suited for Mayu than she is to him and starts to feel guilt for potentially stealing his bro’s future girlfriend (it is also an excuse to avoid women).
The next time Mayu and Mikorin see eachother, Mikorin starts boasting about how great this girl would be for Mayu. It is too much work to explain, Nozaki once again over hears and environs great Manga material so he tells Mikorin he’ll set up Mayu and this date.
Because Mikorin never looked his date in the eyes, he has no clue what she looks like. So Nozaki puts on the same wig and goes on a “date” wirh his brother
Mikorin is Nozy and Chiyo has the insider knowledge that Nozaki is there, so they go to spy on the date, they are sitting in booths such that Mikorins back is turned to the “coulple” and he can only hear what they’re saying.
to his suprise, Mikorin realizes maybe he really did like that girl after all, and begins to get jealous. Chiyo LOVES that girl because she is Nozaki, so she is even more jealous. Chiyo breaks first and puts an end to this date.
Not to sure what happens next but I like the idea of the wig switch and jealous Chiyo.
