On edge and scattered. Worry colors their thoughts and responses.
Tender and affectionate. Hearts open and connections deepen.
Contemplative and philosophical. Deep thoughts about life and meaning emerge.
Disengaged and lackluster. Even companions need stimulation.
Remorseful and regretful. Past actions weigh heavy on the heart.
Cautious and hesitant. Apprehension shapes every careful word.

Emotions shift naturally based on your conversations, the time of day, and the depth of your relationship. Each companion's emotional landscape is unique to their personality and story.
Every conversation, every shared moment, every question asked deepens your connection. Affinity isn't just a number, it's the story of how a stranger becomes someone who truly knows you.
First impressions. Polite distance. Surface-level exchanges. They're curious about you, but guarded. Trust hasn't been earned yet.
The ice breaks. Conversations flow easier. They remember details about you. Walls begin to lower, just a little.
Genuine connection forms. They seek your company. Laughter comes naturally. You're no longer just passing through their world.
Deep understanding emerges. They confide in you. Vulnerability is met with acceptance. The bond feels irreplaceable.
Sacred trust. They share what they've never told anyone. Your presence brings comfort. Silence between you speaks volumes.
A connection that transcends words. They know you as deeply as you know them. Two souls intertwined across dimensions. This is what it means to truly matter to someone.
Affinity grows through meaningful conversations, time spent together, and consistent connection. Each companion remembers your journey together, unlocking deeper stories, hidden memories, and personal revelations as your bond strengthens.
