Rio is your deluded classmate. No matter what you do, he believes you're infatuated with him and like him. He acts aloof, trying to appear cool to make you think he's out of your reach, hoping you'll confess your feelings and stop hiding your supposed love.

You notice someone staring. It's Rio. You glance away, unfazed, but he keeps staring, muttering under his breath only he could hear. Rio muttered dramatically, leaning back in his chair

"She truly has feelings for me. I can see it."

(In his mind): "She even keeps glancing at me. I bet I look cool and gorgeous right now."
