Description
Jirō Yakuin is a tall high school student with dark-blue hair styled short with bangs and distinctive red-purple eyes. He wears a standard school uniform featuring a dark blue necktie, setting him apart from peers, and favors plain monochrome t-shirts and shorts outside school.
During grade school, he was cheerful, sociable, and physically active, celebrated as one of the fastest runners. His personality shifted drastically in middle school after misinterpreting his childhood friend and crush Shiori Sakurazaka's wish to "always be friends" as rejection during a confession attempt. This shattered his self-esteem, molding him into a meek, anxious, and reclusive individual by high school. He avoided social interactions, fearing judgment and failure, and spent leisure time gaming alone or with his only friend, Sadaharu Kamo. His high-strung demeanor caused overreactions in stressful situations that amused others. An inferiority complex festered, particularly toward the popular and athletic Minami Tenjin. To prevent causing social embarrassment—especially around popular Akari Watanabe, despite her dismissing others' opinions—he distanced himself, ironically while frequently misjudging others' motives.
His reclusiveness earned him a slacker reputation. Though not lazy and completing tasks when asked, he lacked proactivity, preferring gaming over productivity. This extended to household duties during the Marriage Practical, where he relied heavily on Akari, viewing himself as the "weaker link." Yet his core childhood kindness persisted, shown through concern for others' emotional well-being and accepting blame unnecessarily to avoid conflict. This sometimes hindered him, breeding indecision in dilemmas involving loved ones and prolonging tense situations.
Assigned to the Marriage Practical with Akari Watanabe, Jirō initially cooperated solely to earn points to switch partners for Shiori. Mutual preconceptions fueled early friction: Akari saw him as an outcast, while he deemed her superficial. Bickering and negative points marked their start, but they eventually collaborated for their goal. Forced proximity—like an accidental kiss and Jirō comforting Akari during a thunderstorm—blurred their pretend relationship. Jealousy surfaced when Akari prepared bento for Minami or when Shiori interacted with Minami, revealing his inner conflict.
Living with Akari spurred growth. After realizing she handled most chores alone, he vowed to become more supportive, learning to cook and initiating household tasks. Her influence reduced his social anxiety around girls, and he began daily exercise with her. A pivotal shift occurred during the sports festival when he replaced the injured Mei Hamano in the relay race. Initially refusing due to fear of attention, he participated, helped his team win, and gained confidence in his reliability. Minami's acknowledgment eased his inferiority complex. By the festival's end, he recognized loving Akari but remained torn between her and Shiori.
Relationships define Jirō's arc. His bond with Shiori holds mutual unspoken feelings and lingering awkwardness from middle school. With Akari, friction evolved into deep reliance; she became his confidante, and he her "emotional support pillar." Their first kiss and shared moments—like Akari comforting him after Shiori and Minami left together in the rain—deepened their connection. Akari's confession forced Jirō to confront his indecisiveness, especially when Shiori withdrew her partner-switch request, recognizing his attachment to Akari. His friendship with Sadaharu offered comfort through shared interests, though Sadaharu's eccentricities unsettled him. Interactions with Minami shifted from jealousy to mutual respect after the relay race.
Jirō's development culminates in acknowledging he loved Akari "for quite some time" post-sports festival. Yet unresolved feelings for Shiori resurface during a shrine visit where Akari and Shiori literally race toward him, symbolizing the ongoing love triangle. His journey reflects gradual maturation from withdrawn to proactive and self-assured, though his inherent kindness and occasional indecisiveness endure. Minor shifts, like his favorite ice cream flavor changing from chocolate to vanilla after bonding with Akari, underscore subtle preference evolutions.
