Synopsis

"Excuse me, I was raised without manners. Prepare yourself, milady." Ava is a noblewoman known as the "Ice Flower" for her cold and haughty attitude. When her engagement was rudely annulled in public, Guy, a handsome and successful merchant, unexpectedly asks her to marry him instead! It is a proposal for a contractual marriage in which both parties' interests are aligned. Ava, who is strong-willed but actually quite naive, gets angry when Guy says he does not expect affection, and she declares, "We can become a loving couple and make each other happy!" That was when he kisses her fiercely. When he whispers love to her with a sweet voice and takes her for the first time, her frozen heart and body will melt into a hot puddle...?
