They are hardly established but I do say they acted like one.
If so, you should try reading Silver Diamond by the same mangaka too.
I absolutely adore them. Both mains are totally super close to each other and hints here and there but they are never properly said or establish. But the plot was gud!!
Does Banana Fish count?

Wow! I really thought this was going to be a shot in the dark. Thank you for the suggestions!
I’m looking for adventure type shounen or shoujo ai mangas, where there is romance, but more as a subplot. Something like No.6, Spirit Pact, or Owari no Seraph BUT the relationship is actually established, rather than hinting at it, like in these examples.
