"Ryu-san?" Sakura asked when she saw the boy flop down in his chair before class. "Are you all right?"
The boy nodded, rubbing his arm. "It's just a bruise, it'll go away."
She got up, and walked over to him, taking his arm and looking at it. "Dad always kissed my bruises to make them better." She gently placed her lips to the discolored skin, and then smiled.
"You'll be okay now!"
... She didn't understand why Ryu was flushing like that.
