Chihiro was internally torn over the two instincts that came quickly to mind; putting his hand over hers or draw his hand away. Eventually, he did both, exactly in that order.

Carefully, he sets his hand on top of her but pull it away much quicker. But that... felt wrong too, but wasn't it rude to do that just leave his hand there as well? Instead of drawing back completely, it was just above Ema's hand. He turns to her with hesitant eyes, waiting for an okay.
