The player character essentially takes the place of Tsukushi Makino. She is a lower class student who enrolls at Eitoku Academy. When the player angers Tsukasa Domyoji of the F4, Tsukushi becomes her friend and ally. The game follows the the manga's plot, only placing the player at the center instead of Tsukushi.
The game functions in an almost real-time manner. For example, the player wakes up, has school in the morning, and sometimes goes on lunch or night outings. They then go to sleep, wake up, and start a whole new day. Tsukasa Domyoji, Rui Hanazawa, Sojiro Nishikado, and Akira Mimasaka are available for the user to date. How much they like the player depends on their affection level. To increase affection levels, the player should go on dates with him, obtain their email address, and other small things.
