Ryoma looked up at the sky, not at all surprised when a heavy downpour started. Momo-senpai had said it would rain and it did, though it wasn't as if he actually had listened to the second year. All he had done was brought an umbrella with him which he quickly opened and held above his head, continuing on his way. He stopped only when he saw the shaking figure of Sakuno and knew the stupid girl had probably forgotten her umbrella. Quietly he made his way over and held his out for her, ignoring the rain which fell heavily upon him.
"Here."
When Sakuno protested, holding her hands up and shaking her head, he merely shoved the umbrella into them and continued on his way. A little rain (even if it was pouring) wouldn't get him sick.
