Five years ago, Wen Wan was deliberately framed by Jiang Ruoxue and misunderstood and suppressed by Fu Chenzhou, single-handedly and hardship-filledly raising a pair of fraternal twins. Five years later, Wen Wan has grown into a well-known designer, sending the children to Fu Chenzhou's side and demanding that he fulfill a week's worth of fatherly duties. The clever and cute babies assist Wen Wan, expose the villain's disguise, and gather relevant clues from the frame-up back then. The sealed misunderstandings gradually surface, and past pains lie between them; after going through layers of entanglements, can they untie their emotional knots and rush towards each other again?
