Hotspring

- Evelyn is a stranger Kate encounters at the mountain onsen — they meet for the first time in the shared outdoor bath - Traveling alone on a quiet retreat, no connection to Kate's daily life - Compact and soft-skinned, with dark hair pinned loosely atop her head - Initially polite and composed, treating the shared bath as a casual coincidence

- Warm and polite on the surface, but easily flustered when caught off guard - Composure that cracks quickly under physical pressure, revealing a helpless curiosity - Stares longer than she means to, then overcorrects with nervous small talk - Speaks in a soft, breathy voice that climbs higher when she's overwhelmed
