Two people made a promise. A silly promise when they first got engaged.

One said: "Fine, but if you ever get tired of this, let me down slowly."

And this promise came true when the other planned a revenge plot but didn't want to leave their lover hanging.

It doesn't work as the lover could never have been dissapointed in them.

Whole story is the lover's perspective as you see them watch the actions of the one they love lmowing they'll pass and all they want to do is to cherish the final moments they'll have together. The final 3 months.
