Candle Queen[Asriel x Urie]

After coming to the surface, and monsters being accepted into society, Frisk finally decides to step into a forest that was claimed to be..'haunted'. That's when he meets Urie, a hollow that roamed the forest alone. Urie would usually kill and or eat anyone that roamed on her 'territory'. However, something told Urie not to kill this human. Almost as if they were...special?

Frisk, frightened, told the first person he saw when he ran out the forest. Asriel. Asriel had mistaken Urie for a human a first..but then immediately knew she was a hollow. Urie would've killed him by now..by why hasn't she?

and what was this..feeling?
