I'm looking for manga where there's a deep and frenemy kind of relationship between 2 Guys. They always fight but still are best buds. It can be a shoujo, shounen, mystery, supernatural, fantasy . no yaoi /shounen ai plz. Although I love it but right now I only need pure male friendship. Manga that I've read are:
It's a comedy/shoujo(?) - about two guys, one a kind of delinquent pervert and the other a smart but manipulative guy and their friendship with one another. They argue with each other a lot, and say they don't like each other but somehow always end up helping each other out. It's very funny and the art is very nice!
I won't spoil it, but there's a reason they argue often I think it's revealed early on, end of chapter 2 or 3?
xxxHoLic and its companion manga, Tsubasa Reservoir Chronicle. The former is a better fit, as the two guys in the latter evolve into proper friends over the course of the series, though the bickering continues.
