The cinematography is good, quite a feast for the eyes while watching. I like the sign language scenes that don't use voice dubbing which makes the dramatization of this drama good.
he had been wondering the Earth all alone and lonely keeping a distance not because he liked being alone, he couldn't hear what others talk about, he couldn't hear when the alarm goes off in the restaurant due to fire. then and there she comes pulling him out of the fire and out of his lonely existence. she learnt sign and smiled when she met him again, it wasn't great efforts just a human nature approaching other human towards the step to make this world a better place.
