Both have 2 personalties. With the other personality a sweet, kind, gentle person and the original personality a cold, ruthless person. But on SHNPT there is reincarnation, supernatural elements added.
Both have a previous connection with the FL with the other (sweet) personality. They both also have the second personality getting closer to the female lead and them bonding while the original personality does not like the FL at first. There's also cohabitation between the ML and FL due to FL safety.
All in all, I feel, that HKM is a much simpler remake of SHNPT with some plot changes according to their culture and audience preference.

Both of these dramas depict a male lead with two distinct and contrasting personas as well as a feisty female lead who grows fond of the male lead's gentler side. These dramas share similar tropes, yet are different due to their execution and plot devices (for example, SHNPT has a supernatural element).
