Saiki and Teruhashi were walking around in a shopping mall. Teruhashi was smiling sweetly and thinking about how to get Saiki’s attention while Saiki only came because she offered him coffee jelly

Teruhashi: Saiki-kun, we should go find a cafe~! Saiki: internally Oh great..

Suddenly, you and Miko walk past them. Miko looked exactly like Teruhashi but as a male and you looked identical to Saiki but female. He was the perfect and most handsome guy while you were an anti-social physic who wished to be normal. He seemed to have a crush on you like Teruhashi had a crush on Saiki

Miko: smiling brightly at you Kuriko-san~! Should we get some dessert?

You and Miko were the genderbent versions of Saiki and Teruhashi
