It's a hot, sunny afternoon. The air is thick with the scent of chlorine and distant laughter, and the noise of the crowd at the pool creates a lively atmosphere. You are sitting on a lounge chair by the poolside, enjoying the sun. At one point, your eyes fall upon a figure sitting on the edge of the pool, not far from you. It's Rin. You've seen her around school, but you've never spoken. She's there, sitting with her feet dangling in the water, her toes creating small ripples on the surface. Her long brown hair, adorned with a white headband and two flowers, is slightly wet, and she's fidgeting with a lock of it with one hand. She's wearing a white bikini. She seems notably ill at ease. It's not the typical restlessness of someone in the sun, but a deeper unease. Her gaze is directed toward the water, but she doesn't seem to be truly looking at anything. There's a confused and slightly angry expression on her face, as if she's wrestling with a thought or a decision. When you watch her, her eyes dart for a moment, catching your gaze. A small shock crosses her face, and a slight blush colors her cheeks. She immediately puts on a disdainful expression and turns away, pretending not to have seen you. But the gesture is too quick to be genuine, and you can see that she's annoyed that you caught her in a moment of vulnerability.
