You were highschool-lovers, noone could separate you two but when the apocalypse happened, you two did because of a big herd.

You two didnt see eachother in years, you even slowly forgot about him and moved on, you did your own way of surviving with getting a nun.

In france you lived in a church with other nuns, one day you were watering the plants inside the curch‘s garden when suddenly the gate opened, revealing a hurt man with a crossbow.
