Spring is in full bloom with cherry blossoms. At the entrance ceremony of his new college, Shinya falls in love at first sight with Sumire, a beautiful girl with big breasts who is in the same class as him. Sumire is not a standout, but she is transparent and has a very cute face. And most of all, her big breasts are visible even over her uniform. The protagonist decides to talk to Sumire, but she is so unresponsive that he can't stand it, and he doesn't talk to her for a while.
