One day, two weeks before her wedding, Ellen encounters her fiancé, Samuel, having an affair. She decides to break off the engagement and look for a new fiancé. However, Ellen is the heir to the Bowen family apothecary, who specializes in poisons. She's looking for a marriage partner who will be a great son-in-law, allow her to be involved with poisons, and allow her daughter to become a pharmacist―are these too many conditions?

I want a loving marriage where we can trust each other wholeheartedly. But the only one who understands me is my escort, Stefan... Will Ellen ever find the man of her dreams?!
