This is a puzzle game in which players match identical tiles to remove them from a mahjong board. In "Endless mode," players are awarded bonus points, stars, and trophies based on the speed of their matches; in "Story mode," players are awarded for completing each level by having portions of a romantic story revealed through old letters and found objects (old photos, hair clips, parchment fragments, etc.). When a letter is discovered, its text is displayed on the screen, and a voice-over reads the letter; some of the letters contain suggestive material (e.g., "My lover, my companion," "My body longs for you," and "I am a scared, silly girl who wants only you, your soft smile, your rough hands touching mine."). The following reference to suicide contributes to the E-10+ rating: "On three occasions, I have pulled the ceremonial dagger from under my futon and held it against my throat. But I could not make the final thrust." One letter also mentions that a commanding officer smokes cigarettes while playing mahjong.
