Lullabye: Single Dad Kars and Son Wamuu
Kars and Wamuu are humans in the 21st century. Kars is a single dad that has to raise Wamuu on his own. They will have lots of time to bond and face the chaos of the world. Also posted on Ao3 I want to write more platonic fanfics for JoJo. I am so happy with this one. Kars is such a great father to Wamuu in this story.
