Description
Hotaru Hinase is the main female protagonist of the story. A first-year high school student, she has never experienced romantic love and initially believes she is incapable of falling in love. This conviction stems from a traumatic incident in elementary school, when a jealous friend cut off her long ponytail. This betrayal left a deep emotional scar, causing her to associate love with pain and misunderstanding and leading her to view romance as something alien and unattainable.

Physically, Hotaru is a petite girl with fair skin and large pinkish-brown eyes. Her dark brown hair is initially neck-length but grows to shoulder length as the story progresses. She wears her bangs swept to the left side and has moderately thick eyebrows. She values a star-shaped hairpin given to her by her family. While she finds short hair more practical for washing, her inability to let it grow long is directly tied to her painful childhood memory.

In terms of personality, Hotaru is kind, introverted, and often shy, but she possesses a strong, quiet sincerity. She is an analytical and serious person who habitually prioritizes the needs of others over her own, though she struggles to articulate her own feelings. Her approach to relationships is thoughtful and intellectual rather than emotional. When the handsome and popular Saki Hananoi asks her out, she does not accept out of attraction but rather from a kind of clinical curiosity, hoping that by dating him she can study and come to understand what love truly is. She is easily flustered by unexpected situations and has a pragmatic, grounded side.

Her journey is central to the story's exploration of emotional growth. At first, Hotaru is emotionally cautious and closed off, viewing romance as a problem to be solved. However, through her trial relationship with Hananoi, she begins to question her own defenses. A key moment occurs when Hananoi risks his health by searching in freezing snow for her lost hairpin. While touched by his devotion, Hotaru firmly rejects his self-sacrificing tendencies, insisting that for a relationship to be healthy, both partners' happiness must be equally important. This moment marks a shift, as she begins to move from intellectualizing love to allowing herself to feel it, culminating in her eventually confessing her feelings and embracing a mutual vulnerability.

Her key relationships include her boyfriend, Saki Hananoi, whose intense and devoted love challenges her assumptions about romance. She also has supportive friendships with classmates Tsukiha Shibamura and Hibiki Asami. Her dynamic with Sohei Yao, an acquaintance from grade school linked to her past trauma, is initially fraught with wariness before she tentatively attempts to rebuild trust. Her family consists of her parents and two sisters, Kagari and Tomori. Her birthday falls on Christmas Eve, an event often overshadowed by her younger sister's figure skating competitions, which reinforces her feelings of being overlooked.

Several small details round out her character. She loves to eat and dreams of tasting food from around the world. Despite being clumsy at sports and once falling heavily on an ice skating rink, she is notably proud of her robust physical health, having never missed a day of school due to illness. She dislikes horror movies and has famously poor luck when attempting to wink.
