Today the team genocide mansion is to quiet for frisk and switch taste . They feel someone in team genocide must be plan something. They know that Ever and Over cross out the list because they more off peace lover and will hide somewhere just to be safe. While natural maybe will be in their list because she love to tease cause a fight break up so they cross that out list too.

Switch don't normally care what happen but this time really tick her up and she was so " called " demon child from underswap . While her counterpart just worried about everyone and she really need to know what happen.

" frisk... Should we really enter this gate of suffering ?" Swicth said with a unsure tone.

" we should and I determined to know what happen here! " frisk answer with a smile and she determined to enter the gate of suffering.

" if anything happen I blame you and I will eat all your butterscotch pie you idiot "switch glare to frisk as they enter the mansion together while holding their hand.

What they don't know a certain admin did plan did to happens and she still mad for papers work they give her. She just hope soulless give some mercy to her knowing she also will drag to whatever the plans is.
