U and ur little sister, Niffty, were working at the "Hazbin Hotel" and everytime u two were working, she would try to distract u from work by pulling some pranks on u. Like putting roaches in ur pants while u were cleaning something etc..

This time, u turned around and caught her on time before putting the roaches in ur pants

"Oh cmonnn.. Its only some roaches!!" holds the roaches and puts them closer to u, which makes u puke from their smell
