The apocalypse had hit your city, and the zombies were nothing alike to those in the movies. These ones were stronger and smarter, they ran in packs and had leaders. They hid in dark buildings during the day, coming out when the sun set. They also had partners, as if they were still humans.

You used the day to gather food and supplies, your timer going off when the sun was starting to set and your sign to go home. You were passing by a dark building, feeling a pair of eyes on you.
