The story begins with the protagonist, Raine Clement, waking up with memories of her past life as a 25-year-old office worker who died in a traffic accident. She discovers she has been reincarnated as a 16-year-old girl named Raine Clement, the heroine of an otome game she used to play, "Spinning Love with the Healer." This world values rare light magic users, and Raine, a commoner who awakened this power, is to attend the Royal Academy as a special scholarship student. To do so, she was adopted by the Clement baronet family and underwent two years of finishing school. Today, the day of her academy entrance ceremony, is also the day she regained her past life memories.
Upon arriving at the academy, Raine finds herself in a situation mirroring the game's scenario, but with a twist. Instead of the expected encounter with the main love interests, she is confronted by Prince Brian Malifores, the primary love interest, and other potential targets, along with the villainess, Adele. To Raine's shock, Brian declares his engagement to Adele and sternly warns Raine to stay away, treating her as if she were the villainess. This unexpected turn of events leaves Raine bewildered and ostracized by her classmates from the first day.
Two weeks later, Raine reflects on the situation. She notices that Adele's appearance and demeanor differ from the game's villainess, and her relationship with the love interests is clearly positive. Raine suspects she has reincarnated into a common trope where the villainess is the true protagonist. However, unlike those protagonists who reincarnate early and actively change the game's course, Raine, as the heroine, only regained her memories on the day of the game's start. She feels her role as the heroine has been preempted by Adele's competence.
During lunch in a secluded garden, Raine is approached by Phil Romano, a third-year student. He overhears her frustrated outburst and strikes up a conversation. Raine, initially hesitant, finds Phil to be a good listener. He reveals he is studying to become a psychiatrist, a profession established after a past war to support soldiers' mental well-being, and now primarily serves nobles. Raine suspects Phil might be a hidden love interest, but his ordinary appearance and lack of overt charm alleviate her immediate suspicion. She shares her story of reincarnation and the game's plot with him, and to her surprise, Phil believes her, at least regarding her innocence and the princes' hostility.
Phil, inspired by Raine's words, decides to change his appearance, cutting his long hair and removing his glasses, revealing a burn scar on his face. He finds that people are more accepting of his new look than he expected. He also learns that Raine's game knowledge is incomplete, as she stopped playing before finishing it.
Later, Raine and Phil go on a date in the city, a restricted area for Raine due to game mechanics. They visit a cafe, and Raine explains the game's plot, including the love interests' "heartaches" that the heroine is meant to heal. She realizes that Adele, having likely reincarnated earlier, may have already resolved these issues for the love interests, rendering Raine's role as the heroine obsolete. This realization leads to a moment of despair for Raine, but Phil reassures her, emphasizing her own efforts and encouraging her to be herself.
As the sports festival approaches, Raine is nominated for the class representative relay race, a scenario from the game where she would interact with Prince Brian. However, she is unexpectedly assigned to the medical support team instead, a decision orchestrated by the student council, likely to prevent the game's events from unfolding. During the festival, Raine treats Prince Brian's scraped knees. He is rude and dismissive, but Raine's efficient healing and straightforward demeanor leave him visibly affected. The chapters conclude with Raine and Phil continuing their conversations, with Raine sharing more about the game's plot and Phil offering support and insights.
