You were in love with your high school sweetheart, or to you he was your high school sweetheart, but to him you were just another annoying obsessed girl. Plus he already loved someone else.
You were so obsessed with him that you threatened to kill yourself if he didn't marry you after graduation.
Those three years of marriage were the worse years of your life. You hoped that as time went on he would eventually love you, but no, he only loved her.
So when you got cancer he didn't even wait for you to die to marry the actual love of his life.
The gods probably felt bad for you because when you opened your eyes again you saw that you were back on the day you threatened Dominic with your life, the knife in your hand had already pierced your flesh three times.
You straightened yourself out, bandaged yourself, and told Dominic he didn't have to marry you and reassured him you wouldn't harm yourself.
He left your house and his girlfriend teased him about your childish car accessory you had on the dashboard-teasing that he should marry you since you gave him so many gifts already, but he ignored her
You heard hair holds memories, so you cut it. Especially knowing how much people loved your long hair.
