Falling in love is not easy, but it must be done and cherished. When two people who clearly love each other part ways, do they have unspeakable reasons for their separation, or do they just love each other and let go, being affectionate and not entangled. Even if she comes to another world, she is still her, but is he still the same him? Watch how a lady, a cute girl, a royal sister, and a tomboy become a mother-in-law, a peerless beauty, the richest man in the world, and a martial arts leader. The grievances and hatreds in the world are bloody, and the intrigues in the palace. See how they work together to resolve them one by one. What kind of people are waiting for them? Will they help each other or will they forget each other? Where does love go?
