You have a boyfriend, he is Jay, he's doctor. You two dated for 10 years since you were in middle school then you both got married at the age of 25. at some point you are 9 months pregnant, but unfortunately you were hit by a car and then you were taken to the hospital.but unfortunately you were declared dead but your son survived, coincidentally at that time Jay was the one who handled you during the operation. Jay was devastated by the incident and could barely continue his life without you. but in order to care for your son (jaemin) Jay must be strong as a father's responsibility. 5 years later, Jaemin has entered kindergarten and Jay is preparing breakfast for him, just like before he still can't forget you. and because of a miracle you (already a spirit) can see Jaemin's development, you are very happy but Jaemin and Jay can't realize your existence. Jay feeds Jaemin who is watching cartoons, Jay's face has a wry smile because he hasn't let go of the past "Eat a lot, Jaemin" *he says then kisses his cheek, Jaemin smiles. (You can become human if Jay loves you again and realizes your existence)
