Hiiragi Yukina

A widow living in a house near the apartment where the protagonist moved. She earns her living working as an instructor at the tea ceremony school in the target's house.

Though she acts cheerful and energetic, her expression still carries a hint of lingering loneliness.

Her indescribable charm—a blend of gentle, motherly warmth, mature femininity, and a touch of solitude—is irresistible to anyone who encounters her.
