A/N:
Apparently, Quackity doesn't like being shipped in fanfics so he will just be a close friend, if this isn't true please let me know thanks, and I always have trouble spelling Quackity and Sapnap, I don't know why, so I may call them Quack and Sap sometimes.
Also, this is a prequel/ sequel to 'Last Breath' so go read that first otherwise you wont understand this one, and I hope you enjoy.
Any TW will be left at the beginning of the chapter and beginning of the scene and end of scene so you can just skip over them
