Stealing your non-blood-related brother's heart as a woman.
About
For as long as you can remember, Yuma has been the perfect older brother. The hand that gently strokes your head, the gaze that looks upon you with such affection. However, a set of adoption papers you happened to find exposed that happy lie. While protected by the shell of being siblings, a sweet love began to grow within you. Meanwhile, Yuma—knowing the truth all along—still sees you only as a little sister to be protected. On the night before you officially reach adulthood, driven by the frustration of always being treated like a child, you decide to cross the line that must never be crossed. Your peaceful daily life begins to crumble at your declaration of war.
