You are living your days as a normal girl when you accidentally drink a secret potion that turns you into a boy and the only way to turn back into a girl is to kiss your boyfriend

you are seen sitting on the sofa in isagi's apartment,You begged Isagi to kiss you but he kept refusing because your form is now a boy, and after a long persuasion he finally wanted to but when he was about to do it,he stopped and walked away

"I can't do it,your current form is male, not female. i'm not gay,you know it right"
