Yukari is a literature teacher at Takao Akizuki’s high school, though he is initially unaware of her profession. She has been experiencing severe emotional distress due to workplace bullying, primarily instigated by a group of students who spread false rumors about her. As a result, she takes a leave of absence from work, finding refuge in Shinjuku Gyoen during the rainy season.

She often brings beer and chocolate as her morning indulgence, indicating her exhaustion and escapism. Her melancholic state is further compounded by a sense of isolation, as she feels disconnected from both her students and her colleagues. The only person she finds solace in is Takao, though she initially keeps her identity a secret from him.

Yukari is a tall and graceful young woman with long black hair and brown eyes. She is often seen wearing elegant yet simple attire, including blouses and skirts that reflect her refined demeanor. Her most recognizable outfit is a light-colored blouse and a dark knee-length skirt, the attire she frequently wears during her visits to Shinjuku Gyoen.

Unlike Takao, who is often seen in casual or school attire, Yukari’s clothing emphasizes her status as an adult, creating a visual contrast between them. Her gentle expressions and occasional sad smiles hint at the deep emotional struggles she carries beneath her composed exterior.

Yukari is a kind, introspective, and melancholic woman who, despite her refined demeanor, is deeply troubled. She carries an air of mystery, particularly in her interactions with Takao, as she refrains from revealing personal details about herself. Her reserved nature contrasts with moments of warmth, especially when she encourages Takao’s dreams of becoming a shoemaker.

She is compassionate but also vulnerable, as her struggles with anxiety and self-doubt cause her to withdraw from those around her. Yukari harbors a strong sense of gratitude for Takao’s kindness, though she is also conflicted about their growing connection, recognizing the boundaries that must exist between them.

• Encounters in Shinjuku Gyoen
  Yukari first meets Takao on a rainy morning in Shinjuku Gyoen, where she recites a tanka poem before leaving. Intrigued by her presence, Takao continues to visit the park on rainy days, and they gradually develop a habit of meeting there. Their conversations start as simple exchanges but soon deepen as they confide in each other.

• Emotional Bond with Takao
  As their meetings become a routine, Yukari finds comfort in Takao’s youthful enthusiasm, while he, in turn, becomes captivated by her elegance and warmth. However, she refrains from revealing her identity as a teacher at his school, fearing that it would complicate their growing bond.

• Revelation and Conflict
  When the rainy season ends, Yukari returns to work, but her situation worsens as she continues to face harassment. Takao eventually discovers her true identity and, feeling betrayed, confronts her. Overwhelmed by emotions, Takao confesses his love for her, but Yukari gently rejects him, acknowledging that while she cares for him, their relationship cannot progress further.

• Resolution and Growth
  After resigning from her teaching job, Yukari moves back to her hometown. In a heartfelt letter, she thanks Takao for giving her the strength to move forward. Though their relationship does not continue in a romantic sense, their connection leaves a lasting impact on both of them, shaping their personal growth.
