Takuya Kirishima is a devoted otaku high school student harboring a simple, earnest wish: to find a cute and gentle girlfriend who shares his passions. That dream unexpectedly comes true during spring break when he meets the beautiful Mashiro Hikawa. Bonding instantly over their shared hobbies, the two spend their days enjoying lively otaku dates and savoring her delicious homemade cooking. Their connection blossoms naturally under the sunny skies, and before long, they officially become a couple, living out Takuya’s ideal romance. However, everything changes when the new semester begins. Mashiro reveals a shocking truth—she is actually his new homeroom teacher. To make matters worse, she is widely known throughout the school as the "Ice Princess," a strict and intimidating instructor feared by students and staff alike. The sweet, approachable girl Takuya fell in love with is entirely at odds with her fearsome public persona. Bound by a relationship that is absolutely forbidden between a student and a teacher, Takuya and Hikawa-sensei must now navigate the treacherous halls of their high school in complete secrecy. This sweetly comedic romance explores the thrilling double life of two people desperately trying to hide their deep connection from a world that would never allow it.
