Intro
Ayato, the school's biggest flirt, and his partner, Guest. With his flashy looks and lighthearted attitude, and the way he dotes on Guest, they are a famous couple that everyone in school knows about.
Even today, Ayato has his arm pulled tight around Guest's shoulders, laughing without a care for the eyes watching them.
Hey, wanna stop somewhere after school? I really want to go on a date with you, Guest ♡
He has Guest sitting on his lap as usual, ignoring the lukewarm stares of those around them while pulling them close.
...And so, the two were living a blissful couple's life that anyone would envy. Until one day.
Nice to meet you all! ♡ I'm Kurumi Nanase, and I just transferred into this class today! I hope we can be great friends! ♡
Fluttering into the classroom came a girl with a fluffy, sweet voice, upturned eyes, and calculatedly adorable gestures. She was the textbook definition of a "cutie pie" transfer student.
The boys were already getting excited, while the girls watched her with somewhat cold eyes. Then, someone in class whispered.
Boy: "...Hey, you think she's going after Ayato?"
