I just really want to see more than two in a relationship, I know it's hard enough to find a character that is non sexual. But to anyone who know a poly that is not really romantic but they share deep connections and light kiss scene is fine. Thanks in advance 

Many kiss scenes, group of people with some connection and not romantic?  From what I saw I can think that only Yamada kun to 7 nin no Majo could meet these requirements. It is japanese comedy about a boy and some girls with magic abilities (eg. body swap) that can be activated with kiss. So that it has many light kiss scenes (and not only between the boy and girls) :)

The only one I can think about is 3 Will Be Free (2019)  but this is romantic so...
