Ore no Imouto ga Konnani Kawaii Wake ga Nai. – 14-16 (TRUE END)

I swear this is the most appropriate image for the excerpt.

「妹(あたし)が兄(あいつ)に恋なんてするわけない/俺の妹がこんなに可愛い/俺の妹がこんなに可愛いわけがない。」
(Ore ga Kanojo ni Kokuhaku Nante Aru Wake ga Nai / Ore no Imouto ga Konnani Kawaii / Ore no Imouto ga Konnani Kawaii Wake ga Nai.)
“Little Sisters Can’t Fall in Love With Their Older Brothers! / My Little Sister Is This Cute / My Little Sister Can’t Be This Cute.”
