Chen Xiao reveals spoilers for Legend of Lu Zhen

When the host asked Chen Xiao to describe one memorable scene in the drama, Chen Xiao picked the candlelight scene (see photos below) because it was he who suggested to the director to film the scene being surrounded by candlelight. This scene was originally scripted to have Gao Zhan and Lu Zhen talking on the bed. Due to his candlelight suggestion, the director got extremely romantic and decided to light up the whole room with candles. Chen Xiao and Zhao Liying ended up speaking only a few lines. They both tried to act with only their eyes.
BEWARE, some ending spoiler ahead! This candlelight scene is actually one of the very last few scenes in the final episode. At this time, Gao Zhan has just succeeded in asking Lu Zhen for her forgiveness after she left him for a few years. He was also suffering from terminal illness and had little to live for except for his love for Lu Zhen. He lost his health, and has given up his power/throne. Okay, let me scream: NOOOOO~~~! These spoilers are boggling my mind with burning questions. Does Gao Zhan end up dying? Or will we have some magic potion to save poor Gao Zhan so he can run off with Lu Zhen to live happily ever after? What on earth did Gao Zhan do to warrant Lu Zhen to leave him for a few years? Can I wildly pray that Gao Zhan faked his terminal illness to get Lu Zhen back?
Conclusion: I will still watch this drama despite some blood-spitting plot devices.
