Cubic has the same tags & same theme as well. Such as: Mafia, Older man/younger woman, strong female lead.

Both dramas have a similar feel, are light in tone with some darker elements, and focus primarily on mystery/investigation with a slow burn romance between the main couple who solve cases together. The ML actor of HDRA is a supporting character (half of the secondary couple) in MM.

Both FLs are quirky, cute, and a bit forward/flirty toward the ML, chasing him first. Both couples work together to investigate cases and solve mysteries. The pacing, tone, setting, and feel is very similar, as well.
