Hi, so I'm looking for slice of life manga about a single guy taking care of a kid!

They don't have to live together, something like a high schooler taking care of a neighbor's kid afterschool is fine too.

No drama/ deep feels (think My Girl) or romance please, especially not between the kid and the caretaker (so no usagi drop or watashi no shounen type manga).

I'd also prefer the kid to be younger, like pre-k/elementary age, and have a good relationship with their caretaker, but something like Sen to Man would be fine, too.

Examples of what I'm looking for:
Yotsubato!
Kakushigoto
Flat (AOGIRI Natsu)
Chichi to Hige Gorira to Watashi
Barakamon
Hyakunichikan!!

Thanks in advance!

Hayachine!
Hisohiso -Silent Voice-
Kyou, Curry!
Madoromi-chan ga Iku.

There's also Baby, Kokoro no Mama ni! where there's some (one-sided) romance, but the main focus is on the childcare. Yuuyake Rocket Pencil is also fairly sweet, though the main child character has a (one-sided) crush on an adult. And Pandora's Choice where the father-daughter pair doesn't get along at all (even worse than in Sen to Man).

There's also quite a lot of isekai child-raising manga now too. For instance, I'm a Middle-Aged Man Who Got My Adventurer License Revoked, but I'm Enjoying a Carefree Lifestyle Because I Have an Adorable Daughter Now (though this one might be a bit too action-adventure and too little slice-of-life). And webtoons such as, Who Made Me a Princess and I Belong to House Castiello. Though, again, these are more plot-oriented than slice-of-life.

Oh, and Nicola Traveling Around the Demon's World could fit. It's a fantasy, slice-of-life travelogue, basically.
