It's just a betrayal in exchange for a time travel. Everyone disguises himself, and in the dark and strife-filled mansions and palaces, we still have what we have.
Everyone is the protagonist, and everyone has his own joys and sorrows. We have too many pursuits, so in the story behind us, there is always someone who silently lights a lamp for you.
The secrets of the Wen family, the royal family... Will be revealed for you one by one.
