Feng Dou Ba Shizi Fei (2022)

In both dramas the plucky, outspoken FL ends up sharing a body with a weaker, more delicate girl who had an unrequited love for someone (ML vs. SML), and who eventually loses her life saving the FL. The lead couple initially dislike each other, but the ML becomes increasingly intrigued by the FL's behavior, leading to him falling in love, and eventually she loves him, too.

Both are mini dramas with a modern day FL who finds herself in history.
