What is the plot?

Episode 397 is a competitive performance episode of The King of Mask Singer, not a scripted narrative with a conventional beginning, middle, and end, and the available search results do not provide a full scene-by-scene breakdown of its performances, matches, clues, and reveals. The year-2023 episode listing confirms that Episode 397 exists as part of the show's run, but the search results here only identify the episode at a high level and do not include its complete segment order or elimination outcomes.

The series format is a masked singing competition in which contestants perform in costume, the panel and audience guess identities, and one singer is eliminated and revealed each week. For Episode 397 specifically, the provided results do not include enough detail to reconstruct the exact chronological sequence of appearances, clue packages, duet or solo rounds, voting results, unmasking, or the final throne outcome without risking inaccuracy.

If you want, I can instead give you a concise episode guide based only on the confirmed information available in these results, or help identify the exact performers and reveal order if more source material is provided.

What is the ending?

I can't reliably tell you the ending of Mystery Music Show: King of Mask Singer, Season 1, Episode 397 from the search results provided. The available sources only confirm that Episode 397 is part of the 2023 run and that it features the reveal of the final part of the winter special, but they do not identify the exact performances, eliminations, or unmasking outcome for that episode.

What I can say, based on the results, is that this episode is structured around the show's standard ending pattern: mystery singers perform, votes are counted, and one or more contestants are unmasked at the end. But the search results do not provide the specific ending scene-by-scene for Episode 397, so I would have to guess, and I can't do that accurately.

If you want, I can still help in one of two ways: - Give you a short, plain summary of the show's usual ending format - Help you identify Episode 397's exact ending if you provide the contestant names or a transcript

Is there a post-credit scene?

No reliable source in the provided results confirms a post-credit scene for King of Mask Singer, Season 1, Episode 397, and the available results do not include an episode recap or end-of-episode breakdown for that specific episode.

The search results mostly point to unrelated clips, general series pages, or other seasons/episodes rather than Episode 397 itself. Because of that, I can't verify whether a post-credit scene exists or describe it accurately from the evidence provided.

If you want, I can help you identify the exact episode title or search for a more specific recap that might confirm whether there is a post-credit scene.

Is this family friendly?

This episode is generally family friendly because it is a singing competition focused on performances, guessing identities, and celebration rather than violence or adult themes. Based on the available description, it does not appear to contain inherently objectionable content, but it may still include loud music, tense elimination moments, and suspenseful reveals that could bother very young children or sensitive viewers.

Potentially upsetting or objectionable aspects to be aware of: - Competitive tension around who will be eliminated or "take the throne," which may feel stressful for sensitive children. - Sudden loud audio from performances, applause, and reveal moments, which can be overwhelming for noise-sensitive viewers. - Masked/unmasking suspense, which may create brief anxiety if a child dislikes surprises or high-stakes competition. - No explicit content is indicated in the available episode description, and the show format is centered on music and guessing games.
