Runa Shirakawa is widely recognized as one of the most beautiful and socially prominent girls at her school. Her easygoing personality and approachable attitude make her popular among students across all social groups. However, her dating history marked by multiple short-lived relationships has led to the spread of unflattering rumors. Common gossip claims that she changes boyfriends frequently, typically dating them for only two to three months, and switches partners without hesitation.

In reality, it is revealed that Runa invests fully in her relationships, but is consistently the one being dumped. Despite her genuine efforts, her relationships tend to end prematurely, not because of a lack of commitment on her part, but due to her partners losing interest. While she is open to dating anyone who approaches her while she is single, she remains faithful once committed. For Runa, dating is a way to understand and connect with someone more deeply, even if romantic feelings aren’t initially present. However, she has never been in a relationship long enough for such feelings to truly develop.

Contrary to the assumptions tied to her fashionable gyaru appearance, Runa is deeply devoted to her partners sometimes to a fault. She often prioritizes her boyfriend’s happiness over her own, enduring emotional strain in an effort to maintain the relationship. Her perception of love and relationships is somewhat distorted, as she believes it is her responsibility as a girlfriend to fulfill any desire her partner may have, including sexual intimacy. She has openly stated that she never sought physical intimacy for her own sake, but viewed it as an obligation to keep her boyfriend satisfied. This mindset, however, tends to drive her partners away, as they find her overwhelming or overly intense in her efforts to please them.

Despite being labeled as the most beautiful girl of the school year, Runa has become the subject of damaging rumors. Some claim she takes advantage of her boyfriends financially during dates or label her with derogatory nicknames like “slut” or “streak.” These claims are either unfounded or heavily distorted versions of the truth, painting a misleading picture of her character.

Runa Shirakawa is regarded as the most beautiful girl in her grade. She has striking blue eyes and long, light blonde hair that reaches the middle of her back, accented by light blue dyed streaks. She typically styles her hair in a side ponytail, adding to her distinct gyaru aesthetic.

At school, Runa wears the standard school uniform, which includes a white blouse, a pink ribbon tie, and a blue tartan skirt. She often ties her blazer around her waist and leaves the top buttons of her blouse slightly undone, giving her look a relaxed, fashionable vibe. Her outfit is accessorized with black thigh-high socks, and she wears blue nail polish on both her fingernails and toenails, further emphasizing her bold and stylish appearance.

Runa Shirakawa is an outgoing and socially confident girl known for her gyaru style and top-tier popularity at school. She is friendly, approachable, and able to engage with people across all social circles without hesitation. Her vibrant energy and openness contribute to her widespread admiration, making her a central figure within the school’s social hierarchy.

Despite her fashionable and carefree image, Runa is deeply earnest when it comes to romantic relationships. While often misunderstood due to the number of boys she has dated, she takes each relationship seriously and gives her full emotional effort. She is loyal, affectionate, and highly attentive to her partner’s needs sometimes to the point of being labeled as “clingy” or “heavy” by others. Her tendency to put her boyfriend’s happiness above her own reveals a vulnerable and self-sacrificing side to her, as she equates devotion with doing whatever it takes to maintain the relationship.

Runa’s understanding of romance is shaped by her belief that intimacy and emotional labor are essential duties of a girlfriend. She often views physical affection as something she should provide rather than something she genuinely desires, which leads to emotional disconnects with her partners. Her overcommitment and intensity, rather than a lack of sincerity, often push her boyfriends away leaving her heartbroken and fueling damaging rumors about her.

Despite the harsh judgments she faces, Runa remains open-hearted and kind. She doesn’t let gossip dictate her behavior and continues to approach relationships with optimism, hoping to eventually experience a meaningful, mutual romantic connection. Beneath her polished appearance and bold style lies a girl yearning for genuine affection and emotional security.

Ryuuto Kashima
Ryuuto Kashima is Runa Shirakawa’s boyfriend and the first person with whom she forms a genuinely meaningful romantic connection. Their first interaction occurred when Runa asked to borrow a pen from him to sign some documents. A few days later, she received a note in her shoe locker asking her to meet behind the gym. Although she anticipated a love confession, she was surprised and pleased to see that it was from Ryuuto. When he asked her out, Runa accepted and invited him to walk her home.

Once at her house, Runa brought Ryuuto to her room, initially intending to offer herself to him believing that physical intimacy early on was expected in a relationship. However, she was caught off guard by Ryuuto’s kindness and respect, as he gently declined and explained that love should not be rushed, especially since they hadn’t even been on a proper date. His sincerity left a strong impression on her.

As their relationship progressed, Runa began to open up emotionally, revealing the emotional pain caused by her past experiences where previous boyfriends had used her for her body and discarded her afterward. In contrast, Ryuuto assured her that he loved her for who she truly was, not just because of her appearance. This emotional support allowed Runa to experience a more authentic and compassionate relationship for the first time.

Nikoru Yamana
Nikoru Yamana is Runa’s close friend and longtime companion since middle school. Deeply protective of Runa, Nikoru is wary of any boys who show romantic interest in her. Her overprotectiveness stems from witnessing Runa’s history of being hurt in relationships where she was often used and abandoned. As a result, Nikoru tends to be highly critical of any potential suitors, often labeling them as untrustworthy until they prove themselves worthy of Runa’s trust.

The given name Runa (月愛) is composed of the kanji tsuki (月), meaning “moon,” and ai (愛), meaning “love” or “affection.” The name can be seen as a variant of “Luna,” the Latin word for moon, which aligns with the celestial theme suggested by the kanji.

Her surname, Shirakawa (白河), combines shira (白), meaning “white,” and kawa (河), meaning “river” or “stream.” Together, her full name evokes a poetic image of a “moonlit, loving river.”
