Kannami Kyoudai no Kunan

Seikain Academy is an exclusive institution for the children of the elite, and among its students are the twins Ouri and Himeri—siblings who could hardly be more different. Ouri, the elder of the two, coasts through his days as an unmotivated member of the soccer club, while his younger sister shines on the honor roll and serves as an assistant to the student council. Their lives could not run more apart—until an unforeseen twist of fate leaves each twin trapped in the other's body. Reversing the switch, however, comes with an outrageous condition: Ouri must seduce Tsukasa Houdou, the revered student council president—while wearing his sister's face and form. Reluctantly, he is forced to step into Himeri's polished world of student politics and play the seductress, a role no ordinary boy could ever have imagined for himself. Meanwhile, Himeri stumbles upon a secret of her brother's—a crush he has kept carefully hidden from everyone. What began as an inexplicable accident spirals into a tangle of hidden feelings, borrowed identities, and an impossible mission neither twin knows how to escape.
