Exactly what it says on the title. Does it exist?

Umm kinda maybe? Shikabane Cherry and Zombie-Loan

This? Kore wa Zombie desu ka? (Novel)

A bit of a spoiler:

Hana to Uso to Makoto .

Franken Fran, sort of. But they're not typical zombies, so I'm not sure you'll like it.

Escape from High-School Girls and its sequel. Both entirely crack, though.

Shinigami to Gin no Kishi - Maybe too unlike real zombies to count.

Shoujo Gensou Necrophilia - Second lead, not the MC himself.

from your question, it doesn't seem like you are trying to find a specific manga but the suggestions given are all related to zombie so try to read them, maybe you will like them for life
i will also give a suggestion

Wake Up Deadman is exactly what you're looking for.

Boyfriend of the Dead. It's on LINE Webtoon and it's easily one of the funniest zombie webcomics I've come across. MC zombie is so lovable.

Dead Days is also a really good one, though the MC is not a zombie :/

Apocalypse no Toride fits somewhat.

Log Horizon ? 🤣

My perfect sentence when someone suspect me : "I'm not suspect, it's not me I swear"

There is boyfriend of the dead but it is a comedy
