Tingyuan and Qingyuan: A Thorny Love Song Beneath the Stars
At 23, Su Qingyuan joins the Li family's Star Design Department late at night, relying on her exceptional design talent. But she unexpectedly gets caught up in an unsolved case: she sees a shadowy figure drop a bloodstained USB drive, which turns out to be connected to the "accidental car crash" involving Li Tingyuan's older brother, the Li Corporation's CEO. Still haunted by an old case from three years ago, Li Tingyuan has become cold and ruthless. He regards Su Qingyuan as a "person connected to the suspect" and forces her to work as his temporary assistant, hoping to use her to uncover the truth and learn the secrets of her father, who once worked for a Li subsidiary. At work, Su Qingyuan faces Zhang Man's bullying and Wen Jingran's help that comes with "a hidden knife." She also becomes a thorn in the side of Lin Ruoxi, the Li family's intended marriage partner. But Su Qingyuan fights back with her design skills, and as she and Li Tingyuan grow entangled, she moves from wary suspicion to glimpsing the vulnerability beneath his hard exterior. The two join forces over the old case, but fabricated evidence leads to a fatal misunderstanding that forces them apart. Su Qingyuan goes abroad to study and transforms into an international designer, while Li Tingyuan, consumed by regret, roots out the traitors within his company. At last, they reunite at Milan Fashion Week and work together to expose the truth: the Lin father and daughter switched materials and plotted to murder Li Chen. They bring the villains to justice. From their suspenseful first encounter in an office building late at night to an embrace beneath the stars at their island wedding, they protect each other through every thorn, composing a love song about truth, growth, and deep devotion with their designs and their hearts.
