Love Case Across Worlds(2021)

Love Case Across Worlds is a Thai series that blends mystery and time-travel romance. Investigator Puncha pursues suspect Dunchaya after she flees a poisoning case. When strange events on a boat transport them both to 1913, their modern investigation becomes impossible. Stranded in the past, they must work together to find a way home—but they're quickly drawn into a serial murder mystery that mirrors the crime Puncha was originally investigating. As bodies pile up in early 20th-century Thailand, the pair races to uncover the killer's identity while searching for a path back to their own time. Their survival depends on solving a case that proves far more complex than either anticipated.
