No One But You is a Visual Novel/Dating Sim about Hideaki, a high school student who has just returned to his hometown, Okutama.
Upon returning, Hideaki re-discovers a town he knew from childhood, meeting new friends and reuniting with those he had long forgotten. He resumes his high school life in the big city, quickly adapting to the change in pace, and before he knows it, Hideaki begins to think of this city as his home once more.

Surrounded by an interesting group of friends, Hideaki lives out his days without a care in the world, content to enjoy a normal high school life. Whether hes going out with friends or studying for exams, his new life is truly peaceful.
