Oh these two cutsie dorks (wich I adore) from Homestuck.
If you’re not familiar with the mess that Homestuck is,
we discover that these two are somehow related via ectobiology in Act 4 (of 7).
That’s why it’s incest.
Basically when they said they were related I went “fuck you I’ll keep shipping them” 3 years ago and I’m still here.
And people hate me for that apparently but whatever U_U
and people conviniently forget that other characters like vriska and terezi or eridan and feferi are related.
