Both dramas have a ghost-seeing human ML and a ghost lead he lives with/falls in love with. Most deal with ghosts turning into evil spirits or crossing over.

The same feel but one approaches as a comedy vs Peach of Time is more melodramatic but the purpose in both are alike really trying my best to avoid spoilers here, but we are dealing with un resolved emotions and unfinished business.
