The Mermaid's Tail

Cordelia is the sole heir to House Marguerite, a family descended from mermaids. After the passing of her mother and her grandfather—the head of the household—her family rapidly falls into ruin. Mistreated by her father and relatives, she is even abandoned by her fiancé's family after contracting a hereditary illness that plagues her bloodline like a curse.

Now, she has at most a year left to live.

Hoping to change her miserable end, she sets off on a journey where she comes face-to-face with Noah Tudor, a beautiful yet arrogant creditor.

When he suddenly threatens her to pay off her father's debts, she proposes a deal to buy herself a one-year grace period.

"Are you trying to seduce me right now because you don't have any money?"

"N-no, I'm not?!"

"Then I suppose I'll buy it. When a lady is this desperate to sell, how could I call myself a gentleman and refuse?"

Just keep acting exactly as you are right now.Because you're so cute, it makes me want to let you off the hook.
