I am a craftsman who restores antiques. After repairing a copper hairpin one day, at three o'clock in the morning every day, I will overlap with the consciousness of Shen Qinghe, the eldest lady of the Republic of China - she can see my modern life, and I can borrow her memories of the Republic of China to find antiques. But as the overlap time becomes longer, we fall in love with the same mysterious man in reality at the same time, and his family actually hides a blood contract curse that spans hundreds of years behind the copper hairpin.
