- Lu Xingci: Twenty-nine, a top-tier star in domestic entertainment, a popular male singer and actor with more than a hundred million fans drawn to his cool, refined stage persona. In real life, he has a charming contrast: aloof on the outside but warm inside. He’s the epitome of chaste elegance onstage, but offstage he’ll learn to braid his daughter’s hair and research baby food. He and Su Qingyuan were childhood friends, but a misunderstanding drove them apart when they were young. At the height of his fame, he refused to manufacture a romance for publicity and stayed true to himself. His hidden talents include soothing a child with guitar songs and accurately interpreting all the different meanings behind his daughter’s cries. His childcare antics have repeatedly sent the “top-tier star dad” topic soaring up the trending charts.
- Su Qingyuan: Twenty-seven, a talented actress and cultural relics education blogger. She was once a child star known as “the nation’s daughter” and successfully reinvented herself as an adult, winning Best Actress for several serious dramas. Independent and clear-eyed, with a sharp mind, she appears gentle but is resilient inside. She rejects the “love-brain” label and focuses on her career and cultural education. In private, she’s a walking encyclopedia of cultural relics and can talk for half an hour about the history of a single shard of porcelain. She reunites with Lu Xingci because they become neighbors, and with a little reverse matchmaking from his daughter, gradually clears up their long-standing misunderstanding.
- Lu Nianyuan: Five, the daughter of Lu Xingci’s distant cousin. After her parents die in an accident, she is entrusted to Lu Xingci’s care. She looks adorably sweet, but is more perceptive and sharp-tongued than her age would suggest. She inherited her mother’s knack for identifying cultural relics and can accurately recognize obscure replicas from Su Qingyuan’s collection. Her catchphrases are “Uncle Xingci’s stage doesn’t smell as nice as my little cookies” and “Sister Qingyuan is a fairy of cultural relics.” She’s the couple’s “super matchmaker” and a “little lucky star” who helps them resolve crises, with the aura of “the nation’s daughter 2.0.”
