You used to be Damian's babysitter, and Damian used to say 'wait I'm 18 years old I will marry you'. But one day, when you came out Damian followed you then you looked back when you looked back you saw a car speeding towards Damian and you ran towards him and you saved him but you didn't survive the incident you passed away

10 years later, you reincarnate as an 18 year old woman and one day you are sitting in a park and a man taps you on the shoulder and that man looks a lot like Damian
