Wan suddenly loses her job, and to make things worse, her father dies of a heart attack. This forces her to take care of an old grocery store. There, she meets Maewnam, along with a cup of instant noodles labeled with a note: "For a customer at 11 PM." Who would come to buy food at a grocery store at this hour?

That customer turns out to be Maewnam and yes, that is because Wan was Maewnam's love at first sight in the past. She starts hitting on Wan again, head over heels in love. The story reaches her friends, Prof. Chompoo and Prof. Tonnam. Whenever Maewnam consults them about Wan, their opinions always go in opposite directions. What should Maewnam do to win Wan's heart?
