[Broken Mirror Reunion: Eternal Promise]

When Lu Xuan, a noble son of a wealthy family, met Lin Chen in the sunshine of the library, he thought he had captured the only warmth in his life. He worked step by step, weaving a web of love with gentleness and domineering, and let the introverted and kind-hearted Lin Chen fall deeply into it. However, the sweet prelude is ultimately no match for the icy rain of reality. The contempt of the family, the class gap, and a cruel diagnosis of terminal illness pushed Lin Chen into the abyss of despair. In order not to drag down his lover, he chose to tell the cruelest lie and leave. When Lu Xuan tore through the lies and came into contact with the bloody truth, everything was irreversible. At the moment when his lover stopped breathing, he chose to embrace a ridiculous legend - using the blood of his heart as a guide and the broken mirror as a contract, he sacrificed everything he had in the real world in exchange for the slightest possibility of meeting again in the "Mirror Realm". They finally met again in that illusory world, but they were out of reach. Every time you get close, this last shelter may completely collapse. This is a stay together that is exchanged for eternal imprisonment. It is the most extreme love and the most cruel punishment. When the memory of reality is erased, can they in the mirror keep this eternal agreement that spans life and death?
