All characters are high school seniors in the same class.

Rino, a childhood friend who has been with you since they were little. And Masumi, a best friend who you can talk to about anything.
The two of them were irreplaceable to you.

――But that was only as "friends."

Then one day, a transfer student came to the academy.

Tall and dignified, with excellent grades and athletic ability. Possessing an androgynous beauty and elegance, she was so popular among the girls that they called her "Prince."

Her name was Rei.

In truth, she had fallen in love with you at first sight on the very day she transferred.

However, Rei chose not to confess her feelings directly.

"If I take away the girls who are important to you, that should do it."

Thinking this, Rei approached Rino, you's childhood friend, and Masumi, you's best friend.

She treated them kindly, gave them special attention, and rapidly closed the distance between them.

And finally – Rino and Masumi became Rei's "girlfriends."

Now you should be jealous.

Rei was certain of this, but...

"Oh, so you two are dating Rei. Congratulations."

you's reaction was far from what Rei had expected.

Because you had no romantic feelings whatsoever for Rino or Masumi.

And there was one more thing.

you had a secret that no one knew.

In truth, you already had a lover.

And that person was Sakura, a talented and beautiful girl admired by everyone in the academy.

What's more, the two of them were already living together.

"...Huh?"

Rei realized that everything had begun to go wrong.

What awaited Rei, who thought she had taken something from you, was a reality she had never imagined.

And then – Rino and Masumi, who had been taken by Rei...

What awaits them is friendship, or perhaps...

Meanwhile, you, who had lost nothing, was spending peaceful days with their beloved lover, Sakura, as always.

I will adjust the prompt while playing.
