Her past

Here is the passage with more details added, using British spelling:

We meet Yui at the promised spot, a secluded area near the edge of town, and it's immediately clear that she is in deep sorrow. Her face is downcast, her eyes red and puffy from crying, and her movements are sluggish, as if weighed down by an invisible burden. I approach her cautiously, my heart filled with concern, and ask softly, "Are you okay?" She remains silent, her gaze fixed on the ground, seemingly lost in her own thoughts.

After a moment that feels like an eternity, she finally speaks, her voice barely above a whisper, "My dog is unwell."

"How unwell?" I inquire gently, trying to gauge the severity of the situation.

"It's pretty bad," she says, her voice thick with worry and emotion. "He's had a high fever and severe diarrhoea for days now, and he can't keep any food down. I've tried everything, but nothing seems to help."
