How the Little Brother Who Turned Into a Girl Became His Big Brother's Girlfriend.

兄貴の彼女になる、女の子になっちゃった弟。

A young man returns to his family home after a long absence, only to discover that his younger brother has undergone a mysterious transformation and is now living as a girl. This sudden and bewildering change completely upends their familiar sibling dynamic, forcing them to navigate a new reality within the confines of their shared household.

The situation grows increasingly complex as old bonds are tested and new, unexpected feelings begin to surface. What starts as a simple family reunion evolves into a delicate exploration of identity, acceptance, and the blurred lines between familial love and romantic attraction.
