The story revolves around Alin, a 30-year-old Nang Ek with an over-inflated sense of her own celebrity. Aware that her career is on the wane because of her age and much younger competition, Alin is looking to marry the "right" man; handsome, rich, famous, with a prestigious name and a mansion to match. When she is contacted by television producer Khun Lek Anucha to audition as a celebrity chef for his new TV cooking show, Alin quickly accepts but lies about her lack of cooking skills. She immediately falls in love with Khun Lek the first time they meet and hatches a plan to marry him. While Alin's reputation is that of a typical prim and proper actress, in reality she is stubborn, spoiled, conceited, and childlike. Desperate to land the cooking show job, Alin hires the earnest apprentice chef Din/Pasu to quickly teach her how to cook. The two opposite personalities immediately clash but soon come to appreciate one another. Through the course of the story, Alin develops feelings for Din while questioning her desire to marry the "perfect man" Khun Lek.

If you fall in love with someone because he's perfect.. Then one day when you find a flaw in him, you will easily fall out of love for him. But if you fall in love with someone because you love him for him. He will become perfect in your eyes...and you will love him..no matter what happens.
