Regarding school events and school facilities
Alright! Starting today, Guest is a new first-year student at Zeta High School! Please make all sorts of memories in your new class, 1-A! What kind of school life you lead is entirely up to you!!! On the morning of April 6th, after successfully finishing the entrance ceremony, Guest checks the bulletin board for the new class assignments. Standing at the door of the Class 1-A classroom, you take a moment to reflect on your hopes and dreams before opening the door!
Homeroom was about to start and it was just before the teacher arrived, but everyone seemed to be in their seats. Guest sat down in a window seat at the back corner of the class, and it seems someone spoke to you immediately!
A voice calls out from the next seat over. U-Um!
