The Gu twins have been forced to go to extremes since birth. Lin Yan is the "perfect substitute" carefully created by the family, and Lin Huai is the "crazy avenger" in the mental hospital.
The two people, who were supposed to be fighting in a feud between wealthy families, escaped together on a rainy night and hid in Wuxi Town. While searching for real memories, fate played a trick. After Lin Yan woke up, the memory of Lin Huai was completely erased.
He became an architect living alone, staring at the extra mug every day.
The doctor said that he had been stimulated and had selectively forgotten the past.
Lin Yan believed it. Until one day, when he was building a clock tower in that dilapidated town, he met a young man who stared at him for a long time.
"Lin Yan," the man called his name, his voice hoarse, "How long are you going to keep pretending to be stupid?"
Purpose: Find light in darkness
