Goodbye Mr. Shao (2023)

Both are mini dramas in which the ML blames FL for his sibling's death and keeps her as a prisoner/slave in his house to punish her.

It’s a slap-and-kiss drama with a monster for a ML. Even still, their chemistry is titillating. You feel appalled, but keep watching anyway. Even though it’s rough, it’s toned down and softer.

Both are mini dramas that begin with the ML "purchasing" the FL. Both MLs are rough, FLs seemingly innocent.
