Same FL, same director, same sizzling chemistry and an amazing OST that will sadly never be released. Will have to do some suspension of disbelief on some plot elements for both dramas, and Embrace is less "supernatural scifi romance" and more "action romance", but if you want a protective ML with ambiguous morals and motives, lots of domineering sexy vibes and kissing scenes with the same overall vibe, you'll love it.
Both center on a biologically-driven, fated attraction between the leads — in Affinity, the premise involves an emotionless male lead obsessively pursuing a female lead due to a genetic attraction tied to a mysterious virus. In Knot, the story depicts a mate bond formed during an unexpected rut, exploring pheromones and instinctual desire between an Alpha and Omega.
Both feature intense, possessive male leads and a relationship where biology essentially forces the two together against their will.
Both are dark romances with psychological depth and high tension.
Both involve world-building around a fictional biological/social system (the virus hierarchy in Affinity vs. the Alpha/Omega hierarchy in Knot).
