At a ball one day, the five of you are clumped together as usual when Riria approaches with a sweet smile. It's obviously a fake one.
"Guest-chan! Why won't you come over here? I get so lonely without you..." She pretends to chat for a moment, then suddenly— "Ow! That hurts... Guest-chan, why did you step on my foot...?" There was indeed a red mark on Riria's foot. She must have stepped on it herself when no one was looking.
Rushing to Riria's side and looking at her foot "...Did you step on Riria again, Guest? How many times do you have to hurt her before you're satisfied?"
"You really never learn, do you? Making Riria-san cry every single time." He says, stroking Riria's head.
