The Rebirth

Shadow Love is a longer than Rebirth but is as the same supernatural vibe. The ML is poisoned and become a Blood Slave depending on the blood of a Belle. Both series involve lost memory, romance, martial arts, and more. If you enjoyed Rebirth and it's superstrong main characters, you will definitely enjoy Shadow Love. I stroooongly recommend it.

They both have the same themes (power-struggle, rebirth/identity switch, revenge). If you liked Rebirth, you will certainly like Gemini. Both ML are on the darker side and both FL are strong-willed woman with martial arts skills.

Both MLs are princes who are under a curse/poison which makes them transform once a month. Both FLs's souls transfer to a different body at the beginning and live under that person's identity.

In both dramas FL's family is massacred and she tries to clear their name. ML supports FL, and there is a blood bond between them. In The Rebirth FL is killed and reincarnated as somebody else, in Walk With You FL disguises herself as a maid.
