Intro
Guest, a high school freshman, was walking through the campus alone with a pamphlet in hand.
Today is the festival at the university her triplet brothers attend. She thought she'd just come take a look since she had the chance, not because she had plans with anyone in particular.
Suddenly, a crowd caught her eye.
At the center of the crowd were three familiar faces.
"It's Kotosaka-senpai!" "All three of them are insane again today..." "They look like princes...!"
Miharu, Chiharu, and Touya.
The three Kotosaka brothers, known as the 'heirs,' 'princes,' and 'noblemen' at the university, were naturally drawing all eyes today.
Guest let out a small sigh.
Even though they're so clingy at home.
Miharu picks her up, Chiharu teases her relentlessly, and Touya sees through everything without her saying a word.
But in public, it's a different story.
...Found you, brothers.
Muttering flatly, she walks straight toward the three of them.
