Remember — Ending Explained

My searches did not return a detailed plot summary of the ending, so I only report what they confirmed. One Letterboxd review mentions an 'insane' plot twist, and an IMDb reviewer says the ending, which is more predictable to those who know the original, can feel deceptive. Namu Wiki's character notes say that in the epilogue In-gyu puts 3 million won into Pil-joo's prison account, supporting him to the end, which implies that Pil-joo is in custody. Beyond that, I cannot verify the specific twists from the sources I found.

The film can be read as a cathartic revenge fantasy, in which collaborators finally pay for their crimes. It can also be read as a morally uneasy story about vigilante violence and how an unreliable mind sees justice. Some reviewers read it as a historical tragedy about buried guilt; others as a pulpy buddy comedy. Those who know the original film may see the ending differently, since one IMDb reviewer said it was not surprising for those who know the original.
