No worries, thanks you for asking.The reason why I put Banana Fish here is because in the japanese manga version, it is originally published in a shoujo type of magazine, which is Betsucomi (Shogakukan). Even though Banana Fish is obviously shounen-ai, I will be listing it here because of the japanese publishing magazine. I'm not too sure, but I think Betsucomi occasionally publish 1-2 shounen-ai manga too. So Banana Fish is probably one of the rare genre publish in that magazine. There's also few more shounen-ai genre manga I'm listing here that was published in shoujo/shounen/seinen/josei type of magazines.
You can find Banana Fish info here on mangaupdates (mangaupdates didn't have the shounen-ai tag genre) : https://www.mangaupdates.com/series.html?id=5753
Hi! I don't mean this to be rude in anyway, but why do you have Banana Fish on this list?
