It’s hard to find anything positive about Aisha and Nex online. These are the parameters I use:
winx club aisha and nex -nabu -roy -tumblr -amino
You can hardly find anything about this couple that doesn’t bring up Nabu or Roy. That’s why I add “-nabu” and “-roy.” As for “-tumblr” and “-amino,” those sites are home to a lot of Aisha/Nex haters (or just Nex haters). Of course, it’s all relative, since most of the fandom hates them.
Usually, I don’t find anything when I search. If I do, it’s still something negative — like a whole video about why Aisha and Nex are a horrible couple. ? Maybe in a year or two, I’ll be able to find positive content more easily. I hope so.
