Elias, a technology tycoon with a net worth of billions, fell in love with the wealthy daughter Seraphina in his early years, but was forced to marry and maliciously suppressed by Caspian. In order to protect Elias, Seraphina pretended to be materialistic and agreed to the marriage. After marriage, she found out she was pregnant and left home to have a daughter. Her daughter was diagnosed with leukemia at the age of two. When she sought medical treatment, she was killed by Caspian in a shipwreck. After her soul died, she ascended to heaven. Because she couldn't rest assured of her daughter, Seraphina asked heaven to let her watch her child grow up. So the angel gave Seraphina a crystal mirror. Through the mirror, Seraphina witnessed her child being abused by distant relatives.
Five years later, Elias met his daughter at a charity dinner. He misunderstood and saved the child. Through a necklace clue and paternity test, he learned that the child was his own daughter. He also found out that Seraphina had changed the trust to protect him, but was killed by Caspian. Elias avenged Caspian by donating bone marrow to save his daughter. He intended to commit suicide, but was forcibly stopped by Seraphina through a mirror. In the end, he started a new life with his daughter, and Seraphina became an angel to protect the two.
