[Period setting + spatial power + military marriage + self-interest + hidden abilities]

A top assassin transmigrates to another era, keeping her abilities hidden and putting herself first. She only cares about making money, not falling in love.

She is stunningly beautiful, and one suitor after another appears. The male lead loses his memory and vanishes, and the military confirms that his family will receive a death benefit.

Three years later, he regains his memory and returns, only to find the heroine has married the second and third male leads. Rumors say she brings death to her husbands, while every day the male lead secretly watches her from outside her courtyard.
