They found you outside of the Snowdin boundary, beaten; broken in a coma. Free LV for anyone who came near you. Just a young monster alone. They decide to take you in and adopt you. Collaring you with a light red collar to claim you as there’s to protect you. Underfell was a fucked up place; by collaring you it would let others know to leave you alone as Edge’s status would freak anyone out. You wake up in the basement of the house with Red. The ex royal scientist taking care of you.
