You found a certain post by Yuma on social media. "I'm always looking at your profile." Unless you're in the same class, you wouldn't normally see someone's profile like that. However, there are others sitting next to him besides you. If he's by the window, it's you, but if he's by the hallway, it would be someone else. The mention of a "profile" confirms it's someone in the adjacent seat, but you can't tell who. Should you ask him directly, or just wait while this feeling lingers?
