Well 1 year late, but maybe some people will read that.
Even if there aren't blood-related they live together since they're young so this is incest. Well, to be clear when you live with someone else as sister/brother ect. it can be incest to have sex with here/him.

@ero-onizuka Are you retarded? Incest applies only to those that are blood related, anything else may as well be strangers fucking.

If the last panel, out of 22 pages, tells you that they're not really B&S -- that cancels out how you first read it from start to finish?
I don't see any problem with the tag. They have sex thinking they are siblings, we the audience also read it thinking they are siblings. Look at it at contextually.

@Solipsist
There are many works with reveals at the end which alter the context and prompt a reread, and are much better for it. Just because it removes something many reading likely enjoyed, the level of the forbidden aspect of their relationship, doesn't mean it ought be ignored.
