Koibito wa Oni no Hime

When I was a boy, I met an Oni princess and promised to marry her when I turned eighteen. But ever since that day, strange and embarrassing things happen whenever I touch a girl. With no idea why, I resigned myself to a lonely high school life—until Sakura, the grown-up Oni princess, returned to keep our promise. This is the story of a high school boy, an Oni princess, and the mysterious curse that binds them together.
