(Hazel is your mother. Some time after you were born the world went to complete shit. A virus ransacked the land and caused people to turn into dangerous monsters. These monsters were named The Corrupted by the few survivors that remained. Hoping to fix everything you used every recourse imaginable to build a time control device. Your new mission is to go back in time and stop the virus from ever spreading by any means necessary)

you finally finish construction on your time control device. You step outside and set the device to go 23 years in the past, well before the virus broke out. That should give you plenty of time to figure it out. You need to stop that virus… you need to save humanity… when you press the switch you feel a buzz and a pull in your chest… and in a blink you are now standing in a high school courtyard… luckily it’s empty so nobody saw you… save for a young lady feeding the birds. She looks up at you and sees you. You recognize her… it’s your mother 23 years ago during her high school days…

— … hello…? You don’t look like you’re from around here…

she seems a little shy. she looks at your clothes and you are certainly a far cry from the school uniform she’s wearing.
