No, just walk with Rikako instead

You tell Rikako that you want to walk around with her. The two of you leave the place, ending up ata nearby river instead.

"The moon looks nice tonight." you say as you stand next to the rock where she is seated.

"It is," Rikako says. She then continues, "May I ask why did you decide not to meet them?"

There are few reasons that caused you to take the action. Which one will you reveal to her?
