Deborah played beautifully by Yoo In-na is a dating coach who gives advice on relationships through her books and radio show. She seems to have a perfect life but it all falls apart when she finds out her rich boyfriend who she thinks is about to propose to her is actually cheating. It is a true to life story with experiences most of us can relate to with how pathetic we can become when our romantic life falls apart. A well acted drama with a good supporting cast who show off different relationships at different stages and the every day struggles people go through in deciding what's right for them.
