Wish the manga would just stick to one plotline, new chapters just don't come fast enough for me to remember or care about all three different stories.
Lol @SkrubsTheNeko there's the main storyline with the brother and sister, then the one with the brother's best friend and this one with the sister's best friend. Now, we should be going back to the main storyline.
This manga may controversial for some people but the friendship in this manga is perhaps one of the most beautiful things I ever read. It just pure friendships.
