I'm caught up on EN story so forgive me if JP has a story that just makes MafuEna the best ship ever or something. But personally I have no idea why people think the two would ever be together. I can see KanaMafu 100% because of the main story but Ena like legit hates Mafu. Not literal hate but she thinks of Mafu as something of a goal and a wall rather than a friend from what I've noticed
I actually ship mizuena more before (I still shipped them :D) but when I saw that one twitter artist...I now shipped mafuena more. Sorry if it's a (really) bad reason to ship them, I know the ship is def overhyped and the other ships like kanamafu and mizuena are better haha. Tho I still hope for more and better interactions/development of them. The power of the internet really changes you
