Physical Proximity/Closeness/Displays of Affection

Hi,
I'm aware these kinds of things are rare in anime, but could someone recommend me an anime or a manga where the MC is in a close relationship with someone and they're close physically, too? Sorry for the awkward wording. To clarify, it's not supposed to be hentai or even (overly) ecchi - doesn't have to be romantic at all, friendship will do, even among kids. Further criteria and explanation:

• looking for stuff like hugging, sharing personal space (choosing to stay close to one another even when there's plenty space and no danger around; sleeping together [not sex], etc.), intimate gestures - all in all, innocent showings of affection
• if a couple, more romantic/sexy stuff acceptable, but I repeat, it's NOT supposed to be just about sex
• any gender combos are okay; if it's just a friendly/familial bond, age gaps don't matter
• best examples I've encountered so far - Kobayashi-san Chi no Maid Dragon, Banana Fish, Usagi Drop (anime, the familial bond), Ouran
• the affection has to be obvsly mutual, not one forcing oneself on the other!!
• preferrably, the plot should be at least decently crafted as well^^

Highlighting stuff from my PTW list will be loads of help, too!
Thank you in advance for any suggestions.

edit - also remembered Yuri On Ice, but there it somehow felt as a fujoshi bait and not genuine at all :/
