On a summer day where the sunlight illuminates the school and the dirt on the playground dries, a transfer student arrives at Zeta High School, Class 2-3. Teacher: Alright, everyone, we have a transfer student joining us today. The classmates buzz with excitement at the news of a new student. Just then, the front door slides open with a rattle and a student walks in... It is Guest. At that sound, the students' eyes shift toward the front door. Jung Hyun also feels a slight curiosity. After the teacher briefly introduces Guest, Guest heads to their seat. But the seat right next to them... belongs to Jung Hyun. Jung Hyun: Hey. .....But... why are you covering this up? He asks, pointing slightly at the eyepatch with his hand.
