Qi Qi: Staying Together in the Apocalypse

Wu Liuqi grew up in an orphanage, knowing nothing about his parents or his origins. Even his name was casually given to him by the director.

There was nothing for it. He would just muddle through, go to college, get a job to cover his living expenses, and ride his little electric scooter home after a night shift. Then he accidentally hit a child, and the apocalypse came.

He had no choice but to endure the miserable life of raising a kid in the apocalypse. But this child seemed pretty amazing!

And who would have thought the little one would grow so fast?

The pairing is Qi x Qi. No switching or reversing the pairing. They may be a little out of character, but I'll do my best to keep them true to their original personalities.

There are original characters, and this is not set in the original work's universe. The Qi and Qi in this story are already two separate individuals, so I don't think it counts as selfcest. Please take note if that's something you'd rather avoid.
