About This Game
This is not a traditional dating sim, but a relationship simulation where your words shape the outcome. Through natural conversation, you build trust and affection. The character will actively care about you, start topics, send invitations, and remember your actions and preferences over time. Three main routes (Friendship / Romance / Special) with open branching paths mean there are no “correct answers”—only endings that are uniquely yours.

Free Conversation: No fixed choices. Talk about anything you like.
Active Interaction: The character will reach out to you with questions and invitations.
Memory & Growth: The AI remembers your preferences and attitude, shaping the relationship as time passes.
Multiple Routes: Friendship, Romance, and Special relationship paths.
Instant Play: Lightweight requirements; AI functions require an online connection.
