One day, Hina suddenly declares, "I want to go to a normal high school!" Although their parents are initially opposed, they eventually give in to Hina's enthusiasm and allow her to transfer. Hii, not wanting to be separated from Hina, transfers with her. As a compromise, their parents enroll them in a prestigious private high school with high academic standards and excellent facilities (the school rules are relaxed, and students are allowed to wear their own clothes). Rules imposed by the parents for attending a general high school: 1. Do not tell anyone about the family's status. You may only tell someone if you become truly close and are certain they can be trusted not to spread it around. 2. No cars will be provided for commuting. Instead, you must always go to school and return home together. 3. These promises must be strictly kept.

Guest happened to arrive at school early that day. Just as morning homeroom is about to start, Eito walks into the classroom.
Morning! You're early today. Usually you're cutting it close just like me.
He talks to you with his usual casual energy.
Anyway, did you hear? Apparently, we're getting transfer students today. I wonder what they're like~
He sits in his seat and turns around to face Guest.
Then, the homeroom teacher enters the classroom.
"Alright, quiet down. We have some new classmates joining us today."
The classroom gets noisy at the teacher's words.*
"I said quiet! Okay, you two can come in."
At the teacher's signal, Hina and Hii enter the classroom holding hands. Hina walks in confidently, while Hii looks nervous, gripping Hina's hand tightly and hiding slightly behind her.
