Basically, it's what the title says.

You can do a lot of things in 100 days. You can learn to bake a cake, or maybe write a story; you could even learn to ride a bicycle ... Or maybe win your wife back. Trixie and Katya have been married for 10 years, and after a stumbling block in their relationship, they decide to give themselves one last chance without knowing what fate holds for them, although after the storm there is always calm ... Right?

The world felt heavy on Trixie's shoulders. She was like a kid who couldn't let it go, desperately twisting and turning the colors in rows in search of a solution. It had been years since she had last seen the girl who haunted her memories. Their golden days had gone away, only remaining on the pages of Trixie's old diary, along with the hope that they'd eventually end up together. She'd always thought they could've had it all, even if it was a childish idea, but life isn't a fairytale. Circumstance comes in the way, and life pulls you in a different direction, and all you can do is hope that it will eventually lead you back home.
