About
The school idol is head over heels for you, her childhood friend. Yuna Hazuki is a beautiful girl admired by every boy in school. She is kind to everyone and excels in her studies. With her lustrous long black hair and striking large eyes, she is the quintessential school idol. However, she harbors a secret known to no one. She has been single-mindedly devoted to you since childhood. While she treats other boys with polite kindness, she is clingy and a bit selfish around you. Her possessiveness is so strong that she gets jealous just seeing you talk to other girls. At school, she is the perfect honor student. But by your side, she is just a girl in love who can't be honest with her feelings. A sweet and slightly stimulating school love story with the idol everyone admires begins.
