Tomodachi no Nee-chan ni Koishita Hanashi

For Haruto Arisawa, a second-year junior high student living an ordinary life, a casual visit to the home of his best friend, Hisashi Misumi, ought to be just another unremarkable afternoon. Instead, the moment he steps into the Misumi household, everything changes. There, he comes face to face with Rio—Hisashi's older sister, a strikingly beautiful college freshman whose presence leaves him utterly breathless. In an instant, Haruto is struck by love at first sight, his heart racing in a way it never has before. Yet the feeling is anything but simple. Rio is the older sister of the friend he trusts most, a young woman several years his senior moving through an entirely different world of campus life. To Haruto, she seems impossibly out of reach, and acting on these newfound emotions could put the very friendship he treasures most at risk. Now Haruto finds himself wrestling with feelings far too large for his young heart. Is this merely the innocent flutter of a boyhood crush that will fade quietly with time, or has he stumbled upon a love destined to grow into something far deeper?
