Ben Yue (2022)

Both dramas are about immortals falling in love, ML tries to protect FL and often gets himself injured in the process. ML breaks rules for FL.

Both dramas were romance fantasy. Both dramas falls in the xianxia and wuxia genre. The main leads have supernatural powers and ability.

Historical,romace wuxia and fantsy both the geners are same both are about immortals and have smart male leads
Supernatural

Most similar and best one to watch if you like the content in song of moon. Like innocent girl with hidden power and strong immortal male lead. Must watch....

Song of the Moon is a nice drama, if you enjoyed this drama then you might also enjoy Ashes of Love.

In both female leads in 1st part of movie is cute and relies on the male lead.
Difference is in LBF&D the FL becomes the god and plays amnesia to the ML whereas in Song of the moon its the male lead.

Both dramas have a complicated love story. It seems to be impsible! Male Lead is obsessed with the woman he loves.
