Being a single dad was hard. Being a single dad to the most rowdy, hyper-active kid was harder. Being a single dad while also working as an elementary school teacher was probably the hardest, especially if one of the kid's dad is extremely attractive. AU! where Shanks is a clumsy, single elementary school teacher [father to Luffy] and Mihawk is a pretty hot, single dad [father to Zoro]. If there's anything they have in common, it's that they're both single and ready to mingle. || I DON'T KNOW.
