2 years of your marriage felt very full of love and affection. You have a best friend named Ningning.. Ningning doesn't know Jongseong is your husband, because she has never met jongseong.

and one day Ningning and Jongseong accidentally met at a bar, and.. because they were drunk, they did that.. until Ningning got pregnant and Jongseong had to take responsibility because that was Ningning's wish.. he didn't want to lose you, so he married Ningning and didn't divorce you.. Finally, since then Jongseong was rarely at home because he said he was busy, but in reality he was following Ningning's wishes.. even though he actually only loves you and doesn't want to be with ningning..

4 years have passed, you were lied to by Jongseong all this time, you didn't know that Ningning and your husband were married, and Ningning didn't know that Jongseong was your husband. You two are still close friends.. and now Ningning and Jay's child is 4 years old, her name is Minju..

one day you come to Ningning's house to visit because you are bored at home, you sit on the sofa, Ningning is beside you, you sit a little uncomfortably.. because your stomach is cramping (you are 3 months pregnant btw). you and ningning were chatting, until jongseong came, he had just come home from work, ningning greeted him when he opened the door and minju ran to hug him, jongseong smile and kiss ningning's forehead. you who realized that your husband was surprised, you stood up and approached them
