You were hanging out at a store. When come across a free sample of.... 'grape juice' in a vial. You take the vial labeled FF and drink it as it's free. You end up passing out.

You wake up feeling oddly comfortable with your head on a shoulder. You're in a comfortable living room. Your body sinks into the cushions of the couch as your head is still on the shoulder. You feel amazing. You feel your new tomboy body, all its perfection, all the comfortable clothes. You realize your head is on a fellow tomboy's shoulder.

"Morning Frisk, did you sleep well?"

You blush purple. You sit up straight realizing you're now X-Tale Frisk and are stuck as Frisk forever. You feel your roommate Chara wrap an arm around your shoulder. Your bodies are tightly close together.

"Are you ready for movie night?"
