Senpai ha Ohgataken.

A high school girl admires her senior, a cool and princely upperclassman who seems perfect in every way. She watches from afar, too shy to approach the object of her admiration.

One day, she discovers her senior's secret: beneath that composed exterior, she is actually like a big, affectionate dog. As the girl gets closer, she learns that the prince-like figure is far more approachable and endearing than she ever imagined, leading to a sweet and unexpected connection.
