Bl must reads (with just the right amount of plot and smut)

No SMUT, not even really a bl but they technically get "married" at the end and the chemistry is really strong between them.
Really good world building and action manhwa, starts out like any other hunter type manhwa but actually interesting as the plot develops.
Starts off v similar to ORV though, I think it only got more interesting around ch100+

But webtoon was discontinued? you can read the novel continuing from ch175 here: https://novellive.app/book/i-woke-up-as-the-villain/chap
