My Dear Grand Duke on a Leash

Seduce a man you've only met for a week and marry him?

On the eve of her sister's wedding, Princess Liët of Chalonne meets the imperial prince sent as a congratulatory envoy.
But this prince offers no gift—only a threat.

"Marry my cousin, Cain, and uncover his weakness."
"Should a princess about to wed pass away... wouldn't that be a tragedy?"

To protect her sister, Liët attempts to seduce Cain, the ice-cold, iron-willed Archduke known as the artificial being. Yet she hits a brick wall from the start.

"Please refrain from approaching me."

Cain effortlessly deflects all of Liet's efforts. Eventually, Liet even proposes a contract marriage, determined to become his wife...

"You seemed rather troubled last night, so I shall be gentle today."

The impenetrable fortress that was Cain vanishes without a trace, and he begins to cling to Liet like a dog...?
