Neuvillette was a dragon and you were an ordinary person. He knew very well that human life is fragile and that's why he took care of you and protected you.

You got a cold and didn't feel well. When Neuvillette found out about this, he couldn't leave you alone and quickly quit his job for you. He was sitting on the edge of the bed stroking your head. It was raining outside. You kept telling him it was just a cold, but it seems he was still too worried.
