The story centers on Fujishima Shingo, an ordinary high school student, and his extraordinary childhood friend, Fujishima Sara (real name: Todo Sarasa), who has become a globally celebrated "God Actress." Despite Sara's immense fame, their relationship remains intimately close, with Shingo initially viewing her as a cherished, sister-like figure, secretly proud of her achievements.
A significant flashback from Sara's perspective reveals the origins of her deep affection and ambition. As a shy child, Sara struggled with social interactions, but Shingo, or "Shin-chan," consistently offered kindness and inclusion. A pivotal moment occurred during a kindergarten play where Sara, disheartened by being cast as the villainess, was encouraged by Shingo to embrace the role's importance. The night before the play, Shingo comforted a terrified Sara by gently holding her as they slept, a memory she cherishes for its profound sense of safety. Following her successful performance, Shingo's heartfelt praise and his casual suggestion, "Sara-chan, you should become an actress," ignited her passion and solidified her love for him. Later, when Shingo's family announced a move to Western Japan, his wistful remark, "If Sara-chan was on TV, I could watch her," provided Sara with a clear, powerful goal: to become a TV actress so Shingo could always see her, no matter the distance. She even adopted "Fujishima" as her stage name, a subtle declaration of her feelings that Shingo remained oblivious to for years.
In the present, Sara frequently visits and stays overnight at Shingo's home, seeking emotional replenishment she calls "Shin-chan power." During one such visit, Sara, cast as the lead in a play with a kiss scene, reveals it would be her first kiss and she wanted to perform it "properly." The thought of her kissing another man ignites a powerful, dark jealousy in Shingo, forcing him to confront his deep, undeniable love for her. During a practice session, Shingo, overwhelmed by Sara's immersive acting, genuinely kisses her, going beyond the script's instruction for a "fake" kiss. Sara, flushed, asks if it was acting. Shingo confesses his love, using her full name, "Todo Sarasa, I love you." Sara tearfully reciprocates, admitting she had "always loved you." Their first real kiss as lovers is playfully interrupted by Shingo's perceptive younger sister, Yuu, who later serves them celebratory red bean rice.
The narrative then jumps eight years forward to Shingo and Sara's wedding. Shingo is now a working adult, and Sara has reached the pinnacle of her career, winning an American Academy Award. Their marriage to an "ordinary person" creates a public sensation. Shingo reflects on how the "fake" kiss incident, though embarrassing, was crucial for him to realize his feelings. He also notes Sara's consistent refusal to genuinely kiss anyone on screen, a secret dedication he understands is for him. Their home life is filled with Sara's playful acting and Shingo's unwavering affection for Todo Sarasa, not just the "God Actress." Yuu, Shingo's mother, and Sara's mother celebrate the union, with Yuu recalling Shingo's past denseness and her own role in their confession night.
Further flashbacks delve into their relationship's development. During Shingo's high school years, Sara, struggling with harsh criticism from renowned director Miyamoto Shinkuro during stage rehearsals, seeks solace from Shingo. He provides comfort and encouragement, leading to intimate moments where Sara, needing a "power recharge," requests deep kisses. These moments, initially embarrassing for Sara, strengthen their bond, teaching them to understand each other's unique perspectives. Years later, Miyamoto reveals his harshness was a deliberate attempt to nurture Sara's talent. Later, during Shingo's university years, a friend's engagement prompts Sara to hint at marriage. Shingo, wanting to be an equal partner and financially stable, asks her to wait, sealing their promise with a kiss. Another high school incident sees Shingo distraught over a test error; Sara comforts him with a lap pillow and gentle head pats, culminating in a soft kiss as he drifts to sleep, solidifying their mutual support and affection.
The story concludes with Shingo and Sara happily married, their journey marked by deep childhood affection, a slow-burn realization of love, and unwavering mutual support through personal and professional challenges, culminating in a strong, loving partnership.
