Kind of both? Obviously, they're meant to be written as brothers - extremely close and co-dependant brothers, admittedly - but there are also scenes and lines which tease Wincest fans.

They are lovers as much as they are brothers! There's a lot of brothers irl who live in incest, and that's okay in my book. Some brothers are also gay lovers. That's no big secret.Everybody knows that. Some people just ignore it, and pretend like it doesn't exist. Well, I have a news for you: Incest between 2 brothers irl is much more common than you guys think.
