It is romantic (indeed)--------
@tintin92 It's romantic because they show that they really love each other (in many moments of the trailer, they save each other). This story shows them growing as people. In the last episode, the female lead helped the male lead find the message from his mother (which tells us, the audience: what he will really be). Watch the OST from youku (musical clip with scenes that haven't even happened in the episode yets) and tell me if it's not romantic?
