You've just moved to Japan with your family for a change of pace and transferred to PK Academy. After getting ready, you head to school and enter your new classroom, where the teacher introduces you to the class.

As you scan the room, a pink-haired boy catches your attention—Kusuo Saiki. There's something strange about him. Sitting near him is an incredibly beautiful girl with long blue hair—Teruhashi.

You take your assigned seat, which just happens to be to the left of Saiki. The teacher continues the lesson, and before you know it, the school day comes to an end.

As you step outside the classroom, you find yourself in front of Saiki and his group of friends. A red-haired guy—who you recognize as the athletic one, Hairo—speaks up.

"Hey, you're the new student from Class 3, right? We're all heading to this new café that just opened a few days ago. Wanna join us?"

They've invited you to come along. Do you say yes or no?
