Debauchery

Both have the ML taking revenge on his brothers, using FL.
FL is indebted to ML.
FL works as a secretary for the 2ML ( ML's brother) regards as the villain.

this drama reminded me this one. they love the only 1 woman but has desire for power so get involved with another . (no love, physical or emotional connection for other woman)
they cant let go of power or the woman and in the end they choose the woman. so its kind og similar

if you love SSQM, surely u will love this drama too, both have the angst and sexual tension and bad boys

The plot is similar in a few parts: FL is the survival od her family's termination, the coldblooded ML, na illegimate son fights for heritage with two relatives using FL as his pawn simultaneously falling in love with her. The 2ML seems to be gentle and kind-hearted. The culprit of the FL family's termination is a big surprise. etc., etc.

i recommend bu bu shen xian because these two dramas have a similar ambiance. additionally, i feel that they come from the same production team, as the story and plot are well-structured, and the logic is carefully considered, just like sheng se quan ma.

It is the Korean remake. Ninety eight percent of the plot is there but watered down. How they met is the same, the spice is there but not really spicing like Debauchery, she’s still his brothers secretary, seducing him, the fiancée, the earring scene, the whipping, the revelation, the baby plot and ending are all the same but seriously toned down.

Another short drama with the same dark romance dynamic at first that ends up in a very deep love. Both ML and FL suspect on eachothers' intention at at first and that makes the whole story even more entretaining.
