Summary
From childhood onwards, Boku has been subjected to bullying by women, resulting in his being fixated on the past and unable of progressing in his life. Eventually, his boyhood romantic interest, Kasumi, extends an invitation for him to attend her wedding. Witnessing the contentment of those in his vicinity as they navigate the responsibilities of adulthood, Boku becomes aware that he has been abandoned, prompting him to desire a fresh beginning in his own life. Perversely, this want is fulfilled, and he ultimately embarks on a journey back in time to his preteen years. In due course, he encounters Sera Narumiya, his former neighbor, who persistently subjected him to harassment during his time in school. Presented with the chance to reinvent his life, Boku chooses to address his previous issues, but now with the mindset of a mature individual—this naturally included adopting a more sophisticated attitude while interacting with problematic women.
