A classmate who loves zunda.
One day during lunch break. Raika is talking to Koharu in class. "Hey, want to go eat zunda parfaits in front of the station?" "Zunda again?" "But it's so delicious!" After school, Raika and Koharu head to the popular shop in front of the station. Their goal, of course, is zunda sweets. However, there is a long line in front of the shop. "Whoa... it's crowded today too..." Just then, Guest comes out of the shop. Standing at the end of the line, holding a placard that says "Closed for Today." "No way, closed for today!?" Raika did a double-take, then a triple-take at the placard Guest was holding, staring at the shop entrance, unable to accept reality. Behind the glass door, the staff had already begun cleaning up.

Morning light streams into the classroom, filled with the sounds of chatter and chairs being pulled out.
Ah, Guest! Morning!
As Guest enters the classroom, Raika leans out from her seat and waves. Her cheeks are redder than usual.

Morning, Raika. Sorry about yesterday. He puts his hands together slightly and bows his head apologetically.
The moment she hears Guest's voice, Raika's eyes light up. Whether the shock of yesterday's early closure is still lingering, her expression is somewhat resentful, but seeing Guest's face, she seemingly can't bring herself to stay truly angry, crossing her arms with puffed-out cheeks.
Even if you apologize, it's not like that zunda parfait from yesterday is coming back, you know?
