This is not an incest manga or a pseudo incest manga (aka they turn out not to be related and get together). The brother ends up with Asuka, his childhood friend (girl with short black hair). They marry and she ends up pregnant. There's even a sex scene. The sister seems to get a boyfriend too, but the guy has yet to show up (his name is Nanase). The manga is weird in the way it shows the brother perving on his sister, but neither of them actually have romantic feelings for each other
