Toffee lost Jack. She appreciated and loved him with all her heart, but he was forcibly dragged into a cult and killed. No, he didn't become a monster, he died. She fantasized to herself that he was actually alive and had become a real monster, and she believed only in that. She made it all up for herself because it was hard for her to get over the realization that her boyfriend had died almost immediately after their long—awaited reunion.
Jack, from another universe, pretended too much that he hated Toffy, even though he loved her very much. He constantly pushed her away, allegedly reluctantly agreed to spend time with her, forbade her to touch herself and basked with him, and he did it with her only when HE wanted it, and it made her happy, even if only for a moment..
Anyway, they were walking through the woods, and Toffee lost the last drop of patience and started yelling at Jack after his next prank. She threw a whole tantrum. Jack, having freaked out, turned around and left her alone in the forest, where, unfortunately, she was overtaken by death. No one knows how she died, but the mutilated corpse was found only after a while.
When Jack visited her grave, he couldn't forgive himself. He hated himself for thinking that she would be there forever. He wanted to hug her again and see her toothy smile, but now he could only hug the tombstone and see the smile only in the photo on it.
As a result, these Jack and Toffee from different universes will somehow meet. I haven't figured out how yet, well, maybe the universe will collapse, IDKKKK
And Toffee? She sees Jack's monster in front of her, sees that everything is real and is like, YES, I KNEW IT, I TOLD YOU SO!!!! I'M NOT CRAZY!
How will they treat each other after the meeting:
Jack will think he's crazy, that he's dreaming, anything, but not that it's true.
