One is a cold-blooded emperor who is obsessed with writing, and the other is a strange woman who is well versed in the market and wealthy. He seeks self-worth in his machinations, setting up a stall and selling paintings in a troubled world, just to find a close friend; she puts profit first, but after meeting him, she is willing to retreat behind the red wall for one person. This is a battle about trust and original intention, and it is also a righteous relationship that transcends identities and grows old together. See how they find true love and meaning among the smoke and mountains and rivers, and build a bright world together.
