Love You to the Death without Regrets

Plot Synopsis

Xu Anci and Fu Sizhen met when they were young and got engaged. Fu Sizhen left to seek treatment, but Xu Anci never forgot about Fu Sizhen and was wholeheartedly waiting for Brother Xiao Si to come back. Ten years later, Fu Sizhen's heart was about to fail. In order to have enough time to find the "Little Cap" (presumably something/someone meaningful to him), he had no choice but to exchange hearts with someone else. There were very few matching hearts, and the female lead happened to be the one in a million match. Fu Sizhen married the female lead ostensibly, but in fact, it was to get the female lead's heart more easily. Unaware of the truth, Xu Anci married Fu Sizhen to save her mother who was in the operating room.
