■ Characters
Sara - The heroine and female protagonist of this game. As a child, she was a mischievous leader exceeding even the boys, but upon reuniting with Leon at twenty, she had grown into a beautiful woman with remnants of her past self. While composed, she is bright, optimistic, confident, and can exhibit a bold attitude. She is very close to Leon, proposing to live together in the same house. Despite showing some girlish shyness, she maintains a close bond with Leon. Although she attracts intense attention from men in town for a specific reason, she has never been in a relationship or had any sexual experiences.
Leon - Sara's childhood friend from an early age, who, after being conscripted, rises to the rank of squad leader but reunites with Sara during his final mission. He is earnest, kind, prioritizing Sara above all else. Despite his lack of sexual experience, he is bewildered by Sara's familiar behavior from the past.

■ Game Content
Based at Sara's home, players will solve various issues in the town. Progressing through dungeon conquests drives the storyline.
■ H-events
H-events are triggered by interacting with each intermediary man, progressively unlocking with story advancement and increasing lewdness.

Special H-events include those triggered on the 5th day and masturbation based on arousal values. These events also unlock with story progression and increasing lewdness.

The ending is determined by lewdness, with three branching final ending patterns:
(1) Happy End (completely avoiding NTR)
Maintain a pure love with Leon without raising lewdness.
(2) Normal End
Engage in relationships with intermediary men but avoid complete NTR.
(3) Bad End (complete NTR)
Fully succumb to an intermediary man.
Bad Endings further branch based on the intermediary man.

■ Erotic Systems
- Intermediary-specific ending branches
By increasing each intermediary man's lewdness, players can choose whom to devote themselves to, leading to complete NTR, insemination, and life years later with the lascivious heroine.

- Post-ending Sub H-events
After reaching a certain lewdness post-ending, the heroine is targeted by men (and some women) in town, allowing players to enjoy mini H-events with diverse situations.

- Cross-sectional views
Events involving insertion feature cross-sectional views, highlighting the differences between the protagonist and intermediary men. This feature can be toggled in options.

- Recollection Room
Previously viewed H-events can be revisited at any time. Viewing CGs alone is also possible.

- H-status
Players can check the heroine's H-status anytime from the menu. As H-events are repeated, the status changes. In the recollection room, intermediary men's H-status can also be viewed and changes accordingly.

- Achievement System
Players can view a list of achievements from the menu, mostly related to intimate encounters. These achievements are attainable through repeated encounters with men.

- Simple Climax Voice, Background Voice
H-events with the heroine's moans include climax and background voices. These can be toggled in options.
