My Lover Is an NPC

Modern people who have read novels basically know what the system is. Scientists in 2111 invented a system specifically for time travel. After many experiments, they found Nanxun. Maybe Nanxun itself didn't have that fate. Halfway through the time travel, the system was attacked by a virus and was forced to stay in the world inside the system. A deserted town. The 45-square lawn, the tombstone in front of the door, the zombies wandering around, and the house without anyone living in it, Nanxun deeply felt that she had been scolded by the system until she even had no pants left. The first person she met in this small town was Dave. Living here alone, I don't understand the world. He was very smart, so smart that he deceived her from head to toe, and then asked her to leave. He was mysterious, handsome, venomous and annoying. He protected her all the way and gave up all his plans for her. Giving up the power to be a human being. He said that because I am an NPC, my love is humble.
