Xia Cheng is a woman without a past. She only remembered that she had a sister named Xia Mo, and Xia Mo had a handsome boyfriend named Wenyuan. Xia Mo was unfortunately abandoned by Wen Yuan. Xia Mo died in a car accident but he survived.
Xia Cheng was surprised that he knew more about Xia Mo than he did. She doesn't remember her past.
In this city that seemed so empty to her, she felt lost. She couldn't remember her and Xia Mo's parents, so she left the city. There was no nostalgia for her here.
In another city, she met a man, he was her sister's boyfriend Wenyuan. Xia Cheng had hated him. She thought Wen Yuan was the culprit of her sister's death. However, getting along more deeply made Xia Cheng increasingly confused.
She fell in love with Wenyuan.
How could this be? What made her hate herself even more was that she actually had the illusion that she was Xia Mo and Wen Yuan was her former boyfriend.
Hope everything is an illusion...
