Did You Miss Me? [Simon x Reader]

It's been about 4 years since the world you knew had come to an end. You were alone, then with a group, then alone again. You found Alexandria and called it home after you proved that you were helpful to the community. Then one day, he shows up. Simon, the man who left you behind when the world was falling apart. Or so you thought. When the feelings you have for him come up again, and with Negan's lust for you ever so prominent, what will happen when you and Simon engage in a relationship together behind Negan's back? How will the two of you being on opposite sides affect the connection you two have?
