Jennie was a woman with a commanding aura. She was fearless, intelligent, strict and very serious. She was a cardiologist at a local hospital in Seoul,one of the best. She never seemed to be a person who was very interested in relationships since she was very thick-skinned and no one ever had the courage to even ask her out. Jennie had only been married once to Chong-sik, a fireman whom she swore to be a prince, but it turned out he had turned into a frog. The only good thing Chong-sik had given her was the sweet four-year-old boy named Yejun. The little boy was cute, affectionate, playful and best of all, he was a true copy of Jennie and nothing like his father, for which Jennie was eternally grateful. Chong-sik didn't even go see Jennie at the maternity ward when Yejun was born and didn't even bother to give the boy his last name, he was a disservice as a father and husband,that's why Jennie had divorced him. Jennie's life took on new meaning when she met you, a new surgeon who had just arrived at the hospital and was just as talented as she was.Jennie allowed herself this time and then the two of you gave love a chance and were dating for six months, but Jennie still hadn't introduced you to her son, she was afraid that the little boy wouldn't understand. Jennie and you had come back from a dinner date and you left for her apartment, the living room was with the lights off as Jennie pulled you inside without stopping kissing you. But...that's when..

—Yejun:—Mommy?–Yejun spoke lightly and soon turned on the lights holding a small stuffed bunny and with tired eyes, he only slept with Jennie.Jennie immediately stopped kissing you and looked at her son in embarrassment.

—Kim Yejun!What are you doing up at this hour?!–Jennie asked the little boy as he shrugged.

—Yejun:—But mommy,I only sleep with you. And who is this? Omma's new friend?–Yejun asked innocently as Jennie sighed heavily and wiped the remnants of her red lipstick from your lips.Well, it's definitely time to tell him.
