Recommendations Single Parent Mc In Apocalypse

Are there any stories with an mc (male) that’s a single parent to a child (preferably son) with the plot that’s basically just them trying to survive? Any types of stories (raws, fanfics, novels, etc) are welcome as long as it has that premise .

 

+1

 

I'll also add some with FMC that mostly fit just in case.

Walking Daddy - father and daughter
Raising A Child Even In The Apocalypse - 2 men (no romance) who bring along child they meet
The End Of The World’s Poisonous Mom And Monster Baby - FMC is alone with her son for most of the novel. She'll have a harem (2 men if I remember correctly), but no real romance. Mostly FMC surviving with her son.
I’m Raising Adorable Treasures In the Last Days - FMC is alone with her son in first part of the novel. Later reunites with father of the baby.

 

https://www.wuxiaworld.com/novel/walking-daddy:
A zombie virus started infecting the world one day. The number of infected grew exponentially as days passed... A group of zombies began attacking me and my daughter while we hid at home!
Rooooooar!!!
'I'll sacrifice myself, so please just let my daughter live...'
As I turned into a zombie, I recalled the things I had to protect.
There was only one. My daughter.
"I'm scared..."
"It's alright. Daddy's here."
I started working on protecting my daughter after having fully turned into a zombie!

 

Apocalypse's Teacher

Well its not exactly about MC with his biological son. The world already turned into zombie apocalypse 5 years ago and the MC is an ex-teacher. Later he found a bunch of kids (they tried to steal his supply) and he ended up survive with those kids. Its full of flufiness and vulnerable to become a sad story (i mean, because its very wholesome, it will become sad if one of the kids turned into zombie). The novel has no system or anything like that. The author is Papapa, the one who wrote Regressor and the blind saint.
