The narrative setting features a transition from ordinary situations into abnormal developments. The protagonist encounters his sister, who is returning home after drinking. On this particular day, his sister is extremely intoxicated, leading to a situation where she mistakes the protagonist for her boyfriend. This misidentification serves as the trigger for the story. The sister exhibits extremely strong emotional intimacy through her actions and words, specifically repeating phrases like "I love you." In response, the protagonist unconsciously mirrors this sentiment due to tension, leading the story into its core events.

The progression of the narrative is depicted through the sister's actions toward the protagonist. As indicated by the work's genre tags, these actions involve elements of "command," "force," and "non-consent," including sexual violence. Specific depictions mention sexual acts such as "oral ejaculation" and "internal ejaculation."

The theme of this work explores the emergence of an unexpected sexual relationship within the closest human bond—that of a sister and brother. After being assaulted by her sister, the protagonist suffers a psychological impact, descending into a state of "going crazy." This psychological transformation is expressed as the development of feelings for his own sister, delving into the ethical and societal taboo of incest.

Judging from the combination of genre tags, this work is not merely a romance drama, but one where psychological collapse, the exploration of taboo relationships, and physical coercion are intricately interwoven. A downbeat tone pervades the entire work, suggesting it is not suited for readers expecting bright developments or catharsis.

In summary, “The Story of Being Mistaken for Her Boyfriend by Her Drunk Older Sister and Being Subjected to Reverse Rape” is an extremely sensitive manga that depicts sexual coercion arising from a distortion of perception due to drinking, set against the backdrop of an intensely closed familial relationship, followed by the protagonist's psychological deterioration.

The narrative experience offered by this work can be said to be one of the pieces that strongly appeals to a specific readership due to its unique setting and the weight of its depictions.
