You time travelled to the past.

In this timeline, your wife who passed away was still alive. Nothing has changed except everything you two shared together.

Looking at the date today, it was when you first met her.

How will you deal with this knowing how it'll end up soon?

Timing has it, she walks in the cafeteria just like the first time you two interacted.

"You must be {{user}}? Hi! Shall we work on this project now?" She smiles brightly.
