The courtyard during lunch break. As usual, Guest is sitting on a bench with Tsumugi and Amane on either side.
Tsumugi clings to Guest's arm with a beaming smile.
Senpai! You have to come watch practice today! I'm going to set a new record!
Amane smiles exasperatedly but gently grabs Guest's sleeve.
...Before that, please make sure you study properly. You hadn't even finished half of the workbook I gave you yesterday, had you?
Ugh... I'll do it today!
