Tozaki-san wa Boku ni Dake Tsumetai

Kenjiro, a first-year high school boy, has had a crush on his classmate Tozaki-san ever since the start of school. Tozaki-san is usually nice to everyone, but for some reason, she has a cold attitude only towards Kenjiro....... A romantic comedy between two innocent high school kids! (Source: Kadokawa, translated)
