She smiled(3)

The girl always came to him, maybe not just for he's her carer, maybe there were some emotions didn't speak didn't need to speak. She followed him, in the messy tools and messy oils and grease, asking him simple questions which were obviously not related to what he was doing, smiling when she found the frown on his forehead was smooth out, then touching him when he immersed in his thinking that maybe sometime made his frown deeper. Everyday, she was with him and he, was with her.

The days had passed, the things were just like what we said in front that seems not had a change. But he knew, a little crevice had existed in his heart and it brought the hot spring out, not magma, like what his father told him love is one thing both very hard to know and very hard to have.
He still was bent on his machines, she was still with great passion to stay with him. Then there came the change.
