Ritsu Kaidou, a member of the top social caste at school, had a boyfriend—not out of love, but because it was what everyone expected.
As their one-year anniversary approached, the moment finally came for their first kiss…
But just then, Yarai Tsuzuri, a quiet classmate, happened to witness it all—!?

This is a story about an ordinary high school girl falling for a cheerful, kind, and slightly airheaded girl with a pretty face.

Reincarnated into the world of an otome game—?
Nagase Matsuri found herself being reincarnated in the world from an otome game.
Her role in the game was to be a “Heroine Support”.
Waking up with her previous life’s memories, she does her utmost best to fully support the protagonist and heroine of this world, Ichinose Maki.
This should mean the heroine would have to constantly lead the love interests on, right? —Or so she thought.
For some reason, Maki shows no interest towards any of the love interests.
This is a love story between Nagase Matsuri, who wants the heroine to be happy with the love interests, and Ichinose Maki, who wants Matsuri to look her way instead.

My first love is my childhood friend, Yamagami Ibuki. For her, I’ve devoted myself to being like a “stand-in wife,” taking care of everything she needs. Our relationship had remained unchanged since we were kids, but as we reached the age of working adults, things began to shift.

“Ibuki, if you end up getting a lover, then say goodbye to me cooking your meals, cleaning your house, doing your laundry, reporting to your parents, or even filing your taxes!”
“W-What? Why?”
“Because… if someone’s coming over to your house at least three times a week and frequently staying over, that’d be unfair to your lover!!”

Ibuki is a hopeless person who’s left all the housework to me. This can’t go on. For her own good, I need to distance myself. At least, that’s what I thought—until Ibuki started pulling tricks she’d never tried before to keep me around.

“Alright, fine! Yukino, let’s get married!”
“W-Wha!?!”
