The God of Small Things (1997) is the debut novel of Indian writer Arundhati Roy.

Blood Brothers is a musical with book, lyrics, and music by Willy Russell.
 The story is a contemporary nature versus nurture plot, revolving around fraternal twins Mickey and Eddie, who were separated at birth, one subsequently being raised in a wealthy family, the other in a poor family.
 The different environments take the twins to opposite ends of the social spectrum, one becoming a councillor, and the other unemployed and in prison.
 They both fall in love with the same girl, causing a rift in their friendship and leading to the tragic death of both brothers.
 Russell says that his work was based on a one-act play that he read as a child "about two babies switched at birth ... it became the seed for Blood Brothers."
The chapters of the manga series Boku wa Imōto ni Koi o Suru were written and illustrated by Kotomi Aoki.
 Originally serialized in "Shōjo Comic", the individual chapters were collected and published in ten "tankōbon" volumes by Shogakukan, with the first volume released May 26, 2003; the last volume was published on August 26, 2008.
 The story focuses on fraternal twins Yori and Iku, who fall in love with one another despite being siblings and struggle to deal with their illicit relationship.
