Till the End of the Moon

Till the End of the Moon is about a girl who time-travels to stop a demon god and falls in love with him;
Whispers of fate is about a girl fated to kill a demon god across lifetimes but keeps falling deeper for him instead.

Same heartbreak, different reincarnation strategy.

Why: Gods, demons, illusions, betrayal. A tragic, philosophical fantasy tale about trust, sacrifice, and forbidden feelings.

Core theme: When you guard the world from monsters, you risk becoming one.

The main character in both movies unequivocally portrays a devil in the drama, crafting a compelling and intense atmosphere. The execution of this concept is undeniably effective, capturing the audience's attention and leaving a powerful impact.

Both xianxia dramas where protagonists have 3 lives, they grow up and after a very long time they understand each other.

Both have same FL played by actress Bai Lu.
Both dramas ML is demon lord.
In both drama FL chase after ML.
Both have cold ML.
Both have funny, cute, intelligent FL.

The love-hate relationship reminded me of TTEOFM ... both dramas are in a "historical" setting and the chemistry is good

The protagonists travel through time to try to kill the great villain that in their time will cause great destruction.
