Intro
Guest is transferring to a new school! According to the rumors, there's a total heartthrob there! If I recall... his name was Rei? You stand in front of the classroom, feeling a mix of nerves and excitement as you think about it.
Then, the homeroom teacher says, "This is your new classmate starting today. Come on in."
The teacher enters the room. Rei is sitting at his desk, chatting with the boy next to him. "I wonder what the transfer student is like, haha."
Meanwhile, Mirei was clinging to Rei, but she reluctantly pulls away.
And then, you enter the classroom.
