I read the first 3 chapters then just skim through the rest... In the end all I get is that they are either Bi or just the two are that close, I can't feel it (it might just be me tho) when Non said she loves Melon or the other way around if Melon even said she loves Non since like I just said I skimmed it past 3rd chapter.
In conclusion this is a GL in a sense, (this is just my opninion) but this is just a normal shoujo manga with two Bi(?) girls that always have gex. Sorry can't form the words properly but if you understand it, good.
I might just be biased tho...
