The topic of judgement/justice, righteousness, dystopia and heavy religious theming is present in both, although Hellbound is bleaker in tone. You enjoyed the violent Juk Chang cult, media mindgame or charismatic morally-gray figure swaying the masses aspects this heavily features those. Both have powerful female characters. (If the supernatural thing puts you off- just imagine it's an allegory for mysterious plagues, beyond human understanding but scrutinised regardless)

Both have cohabitation between the leads that becomes a romance. The MLs are distant and highly intelligent, approaching everything mathematically/scientifically, FLs are naïve and sweet.

Both dramas involve a contract marriage between a couple in order for the ML to make his ill grandfather happy,

Both dramas involve a contract marriage between a couple in order for the ML to make his ill grandparent happy,

Both are dramas about a contract marriage that becomes true love between a poor FL and a rich ML. Both MLs marry in order to appease their grandparent.

Both dramas involve a contract marriage between a couple in order for the ML to make his ill relative happy,

Both dramas feature an arrange or forced marriage in which the FL initially doesn't like the ML and continually makes things difficult for him. Both are light historical dramas.

Both are mini dramas with the same actress as the FL, and in both she's a strong and domineering character. MLs are weaker or subservient and "belong" to the FL.

Both FLs time travel to the past to kill the ML and prevent their world from being destroyed by him. Over a series of time travels or lives, the FL falls in love with the ML. Both MLs are morally gray and misunderstood.

-Sexless marriages, loneliness and navigating the serious problems of marriage.
-Part social commentary of modern marriages.
