[Kuroko's Basketball] Haruko and Atsuko

I don't know why, but the title makes this seem like a yuri story, when it's clearly romance! These are little snippets about two childhood friends who grew up together. The heroine is Momo's younger sister (D cup, need I say more?). The rival and Murasakibara used to be a couple (or so it seems). Older woman-younger man romance. If that's not your thing, read with caution.
