In the Clear Moonlit Dusk 2 (manga)

Yoi Takiguchi’s handsome face and gallant manners have made her a “prince” in the eyes of her peers, but in truth, she harbors a complex toward the nickname. Then she meets Ichimura-sempai, the school’s other “prince,” whose inner thoughts are as elusive as the Moon on the water. Despite her terrible first impression of him, Yoi realizes she’s becoming more and more drawn to him—and even suggests that the two of them try dating (as an experiment)! Does Yoi really know what she’s signing up for…?
