The trio "blonde, black, pink" is kind of a classic, you know
(Nobara almost fit in... she might have been a rare blonde female, but okay)
This is a typical shounen trio, lol, and not only this genre, right? Also romcoms. Because of the existing cliche, you can at least say that such characters in the title will have a special connection, and at most you can ship them 🤭 which is what happened with my ocs, lol. I didn't even try on purpose (and that's why it's even cooler), but they turned out to be that very blonde, black, pink team 🤜🏻
But I like how the cliche is played up a bit with them. All the blondes are guys, but my Sigyn is a woman, and very much a shounen protagonist with a lot to achieve. The black boys are always very unhappy and withdrawn, but my Erich is a social mess. The pinks are more diverse, so it's not at all surprising for my pink daughter to be cute, but with a double meaning... haha.
