Both series have New Thitipoom in lead role. Both are very funny with similar comedy styles. There're also some mystery thriller vibes. If you enjoy one of them, you should check out the other one.
Hidden Moon is rather like if you took one of the haunting-of-the-week episodes of Peaceful Property and stretched it over a full series to truly flesh out ghosts. It plays with many of the same themes of loneliness, grief, guilt, and societal injustices, as well as the concept of healing these wounds by listen to people's stories and making right what you can. A particularly good match for anyone who really enjoyed ForceBook's story.
