I watched this, partially b/c I like Xu Kai and Zhao Lu Si, but also b/c I was hoping it would NOT actually be the incestuous story the description made it out to be. From the get-go, they had 15 year-old brother Jun Xi looking at his little sister like he was (romantically) in love with her. And that was BEFORE any of the characters realized she was switched at birth. Like, what the actual crap? Are we going for a Jaime-Cersei vibe here? It is so weird to have a young teenage boy be in love with his sister. And it's not much better to have them fall in love when they're adults, after the truth has been revealed and they've been apart for some years. I mean, it's still very incestuous feeling; they grew up believing they were brother and sister! And then I was thinking (hoping), maybe it's one-sided and she'll reject him as soon as she realizes, but nope. Her little kiss on the clear plastic/glass while he was sleeping next to his painting made it clear that wasn't the case.

Reading through other reviews / comments, it seems like a lot of people were confused at the end as to who she married. I don't know why. People are also calling Xu Kai the male lead. Looking at the poster will clear both of those up right away (and if looking at the poster doesn't clear up who the main ML is, then just look at the cast list - Xu Kai is the second male listed.) The poster clearly shows Xu Kai off to the side while Zhao Lu Si and Jiao Rui in an embrace about to kiss. Plus, the wedding scene showed Han Tai (Xu Kai) walking her down the aisle, but he was essentially playing the role of a father in a Western wedding, handing her off to the groom, who was Jun Xi (Jiao Rui). Chinese weddings have adopted some things from Western weddings, but even when they've adopted certain customs, they often do them differently than we do. I think it's pretty clear she married the brother and then died, hence him walking alone through the tunnel.

Anyway, I gave this a 6, mostly because I know the actors are good actors and the production quality and music were OK, but the brother-sister love thing is just too weird for it to get any higher rating than that.
