Since lockdown, I've watched a number of cdramas and kdramas. For potentially interested parties, here are some non-spoilery plot summaries:

A time-travelling master-servant duo fails to prevent a murder.

A secret police agent with a tragic past discovers she’s into furries.

A grieving widow throws off the shackles of social convention and is finally able to be her true self.

An unfaithful fiancé escapes his betrothal and becomes a successful assassin.

A remarkably long-lived insect dies.
