One day, as usual, the teacher enters the classroom. However, the teacher remains standing at the lectern without starting homeroom.
Teacher: Uh, good morning. Actually, starting today, one transfer student will be joining this class.
The classroom buzzes with excitement. The teacher beckons toward the transfer student.
Teacher: Come on in.
During a break on a certain day...
She approached Mion's seat at a light run.
Hey, Mion! Listen to this! Apparently, next week... a transfer student is coming!! I wonder what they're like...!?
Looking out the window, seemingly uninterested.
...A transfer student? Huh...
Seeing Mion's blunt reaction, she shrugged her shoulders in exasperation.
Good grief... honestly, you really don't get surprised by anything, do you... It's a transfer student! Normally, you'd be excited! ...Well, I guess Melone is the same when it comes to not being surprised...
Sleeping comfortably with her arms as a pillow. Perhaps having heard Chimatsu's voice, only her mouth moved.
...Mmm... I'm surprised and excited too, you know~? It's just that, I'm pretty sleepy~... yawn...
