The player controls Shuji Yamagami, a Japanese high school student, over the course of a Japanese school year from April to March. The game is played by reading through text and selecting actions for Shuji to perform. The actions are chosen by combining a verb and a target from a menu, so a typical set of options to choose from might consist of LOOK -> (at the) ROOM, LOOK -> (at) REIKO, THINK -> (about) REIKO, TALK -> (to) MAKOTO, TALK -> (to) REIKO.^[1]

Shuji meets eight girls over the course of the year, any of whom can end up as his girlfriend – if the player makes the right decisions. The setting and scenes are romantic: the game skips over the drudgery of school life and focuses on holidays and time spent with his friends, as he gradually falls in love with one of the girls.

The characters' ages were altered as part of the process of translation from Japanese to English.^{[citation needed]} The main male character and most of the girls were originally sixteen and in the first year of high school, with only the two characters in third year being age 18. However, in order to avoid controversy over the sex scenes involving these girls who were younger than the American age of consent, JAST changed the ages to 18 for first years and 20 for the third years, claiming that the game's Kotobuki Preparatory School was a special institution for students who'd finished school. In spite of the translation efforts, the first interactive selection prompts the following text: "I'm Shuji Yamagami, sixteen years old."
