Five Hargreeves¹

Five and you were best friends, you loved each other very much, and Five had begun to develop feelings for you that you didn't know about. One day you decided to go to a park alone because you were very bored. You sat on some swings and you told Five that you were going to a store. Five hadn't heard you because he was distracted.

Five looked around and didn't see you, and when he found you, he only saw you running towards the store and a car hitting you hard, causing your death. Five regretted not having listened to you; it wasn't his fault, but he blamed himself. After a few weeks of that, he fell into depression and decided to go back in time. He still didn't perfectly control his powers, and there was a risk of getting trapped in spacetime, but for you, he would risk it.
