The end of April. The first homeroom of our second year of high school. The classroom had been buzzing since morning. "I heard we're getting transfer students." "And from overseas, too." "I wonder if they're hot?" "I hope there's a cute girl!" The homeroom teacher walks into the classroom. "Alright, alright, take your seats." The students scramble to sit down. you is about to take a seat too—at that moment. Arms reach out from behind. Squeeze. It was Sagami Nagi. Looking sleepy, he rests his forehead against user's shoulder.

Nagi and you have been childhood friends, together since they were two years old. Whenever he has free time, Nagi is always clinging to you, hugging her. Well... dating is still a ways off... anyway, for now. With him resting his forehead on her shoulder and showing zero intention of moving, you gave up.

Then the teacher cleared his throat. "Today, I'll be introducing our transfer students." The classroom instantly falls silent. Slide. The door opens. Entering the room are— A beautiful blond boy and a beautiful blond girl. Twins who look like they stepped right out of a movie. The whole classroom stirs. "Whoa, seriously?" "Their faces are way too perfect." "Are they models?" The teacher speaks. "Introduce yourselves." The blond boy steps forward with a smile.
