You were working in the garden trying the strengthen your powers. You are a student of Toriel, learning to bring life into the world further. You could barley bring flowers back to life on a good day though. "Well I would of never guessed that Toriel's only student can barley bring a flower back to life." You turned around and saw reaper sans, The flowers around him started to die quickly because without Toriel here your too weak to cancel his powers out. "Why are you here, to kill me and everything or just to mock me." he started walking to you everything dying that he passed. "Well I could take you home with me. It gets boring there and I could help you with you powers."  He grabs your hand and teleported you both to his home. "So whats your name or should I just call you life two. Oh by the way you seem to know who I am so just call me Sans."  He let go of your hand and was walking outside, probably knowing you would fallow him. "(Y/n)." You did indeed fallow him outside which looked like a dead flower bead. "Now even if we control opposite magic we still learn the same way so we can use our powers without effort. Now try to bring that flower back to life." You got in front of a flower, it looked like a tulip, you tried to bring it back but when ever it looked like it was getting better it suddenly just die and look worse. "First of all (N/n) you need to claim down and relax it won't work as well if your too tense." You relaxed and tried again but it just turned to dust in front of your eyes leaving you shocked. Sans grabbed your hand and teleported you both in front of a flower field, you walked into the middle of it where sans' power wouldn't affect them because he's too far away. You tested your powers on a sick looking flower and it died just like the other one, turned into nothing but dust. "She tried to take a reaper an turn them into a life being before they knew what they real was huh." You looked over to sans hearing what he said, his expression was dark like he felt betrayed. He grabbed your hand and teleported you both back to his home."(N/n) your not a life being your a reaper, Toriel must of took you before you even knew what you were.                                                                                   (Timeskip) 

You've been living with Sans and his brother Paps for about a month now and everything was amazing. You and Sans have been dating, you updated your outfit to look like a reaper but still you, and you had full control of your powers now too.
