Yan Boyao, a son of an aristocratic family, met Wang Shuimo, his girlfriend when he was studying in Los Angeles, again after four years. Seeing her smiling as she interacted with various men, he found that he still missed her so much. However, he understood that they could never go back together. Not to mention that she quickly found a new boyfriend three months after breaking up with him. The most disturbing thing was that she was pregnant with someone else's child.
Wang Shuimo didn't expect to see Yan Boyao again. The poor student four years ago turned out to be a suave and wealthy man. It turned out that she thought she could only remember his back in this life, and she could only blame her for being too naive. She thought it was just a small quarrel, but it turned out to be an excuse for him to leave her. From then on, there was no news, leaving her to suffer all alone on the other side of the ocean. As much as she loved him in the past, she now hates him as much as she loved him.
Four years later, they thought they had gone a long way. Unexpectedly, the past they each thought still locked them tightly in that small apartment in Los Angeles...
For four years, they have not stopped loving each other, but this relationship is wrapped in a lot of resentment. They wear armor with thorns all over their body, ready to stab each other at any time. How can they let go of their hearts and turn the past into treasure?
