The protagonist begins cohabiting with his girlfriend, Kanako Tsukishima, whom he started dating in college. Compared to their sweet romance, living together presents many practical challenges. Players must plan their daily lives, balancing academics, lifestyle, and romance. Fulfilling Kanako's physical and emotional needs is also crucial as her boyfriend. Too much intimacy may lead to her dislike, while a lack of it is, of course, unacceptable. The 26 weeks the protagonist and Kanako spend together will determine their fate (ending). This game features an auto-save system. To enhance realism, the player's past actions are recorded, and conversations with Kanako and her reactions will vary. Failing to properly listen to her may result in being dumped.
