"I Can't Believe I Slept With You!" is a romantic comedy manga that explores the complexities of relationships, misunderstandings, and personal growth. The story centers on two main characters, Aoi and Haruto, whose lives become intertwined after a drunken one-night stand. Aoi, a reserved and hardworking office employee, struggles with self-esteem and trust issues, while Haruto, a carefree and charismatic bartender, hides his own vulnerabilities behind a playful demeanor.

As the narrative progresses, Aoi and Haruto attempt to maintain a platonic relationship, but their mutual attraction and unresolved feelings complicate matters. The story delves into their individual backstories, revealing past traumas and emotional baggage that shape their behavior and decisions.
