Blade's Dance with You (2024)

TOO many similarities where both FL and are assassin and got a task to kill the ML and to get close to the ML, the FL pretends to be a bride and gets married to the ML. BDWY is short drama and MJTY is long drama

The two plots are very similar. The female lead is an assassin too and the male lead has a job releated to the government.

Both are historical mini dramas in which the FL is an assassin who marries the ML in order to kill him. Both leads have a past connection which the ML discovers first.
