Swordsman (2020)

Same Theme of Father saving his daughter.
ML is a secret warrior in both cases, who is living a secluded life.
ML has to revert to their old selves in order to protect their loved ones.

3 warriors from the Goryo Dynasty lead a riot. Due to the betrayal of Deok-Ki (Lee Byung-Hun), Poong-Chun (Bae Soo-Bin) dies. Deok-Ki then tries to persuade Seol-Rang (Jeon Do-Yeon) to join his side, but she refuses. She then flees with Poong-Chun's sword and his infant daughter.

18 years later, the female warrior is now blind and she trains the young woman (Kim Go-Eun) to use the sword for revenge. Meanwhile, Deok-Ki is the most powerful man in the country. Soon blood will be shed.

Similar story where the ML saves a family member taken away from him. Something happened in the past and they now live peacefully far away. But somehow they get tangled up with the bad guys.

Both have Jang Hyuk in amazing action choreography , one is with swords other is with Guns. both are about saving teenage girl .
