Earlier, Shui Xian could easily move his hand away from the reach of that delusional woman who thought she could get his attention but thinking about Raelle, he didn't do so. Of course, he wanted to see how she was going to react. He, not even for a second believed that Raelle would let a stranger even put a finger on him. He clearly remember that she didn't like people eyeing her things. And he was labeled as HERS!
She asked him a question before, won't he get tired of loving her all on his own?
Now, he really wanted to tell her, who said she didn't love him? The people she called hers were all the ones she loved. Whether she knew it herself or not, he had come to understand it all. With her protecting him, being possessive about him, how was he supposed to say she didn't love him? Wasn't it all love?
