Very different setting (modern day vs. historical) but both are about mental health and helping people.

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.

Both dramas have a similar feel and pacing, are historical with mystery and a slow burn romance, and are lighter in tone.

Playful, more extroverted ML who wears darker clothes flirts and tries to attract attention of stoic, white-wearing other ML who seemingly ignores his interest but is actually affected and despite not outwardly showing as much affection, he tries to protect him against dangers,
