Welcome to the Oniichan no Koto WikiEdit
You can find the Wikipedia article about this series at Wikipedia:Ochinko. The name ochinko.wikia could not be used probably due to "chink" being censored.
The full title is お兄ちゃんのことなんかぜんぜん好きじゃないんだからねっ!! which is pronounced "Oniichan no Koto Nanka Zenzen Suki Janain Dakara ne—!!" which means "I Don't Like You At All, Big Brother!!"
It became more popular in 2011 when a thirteen-episode anime adaptation was made.
