To Heart 2 is a romance[1][2] "novel-type adventure game" in which the player assumes the role of Takaaki Kouno, who begins his second year of high school after reuniting with a childhood friend.

Throughout the game, the player encounters CG artwork at certain points in the story, which take the place of the background art and character sprites.

To Heart 2 follows a branching plotline with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction.

Text progression pauses at these points, and depending on the choices that the player makes, the affection rate of the heroine associated with the event will either increase, decrease, or remain the same.
