"Till the End of the Moon" was originally supposed to have two parts with the first half spanning 34 episodes and 24 episodes for the second half, but the production team had condensed everything into 40 episodes, in an attempt to speed up censorship checks for the drama.

Episode 40 was cut that was EP 58. I think. The novel in Thai translation has 4 volumes.
