My initial interest in this was due to the stark contrast between 1-star and 5-star reviews, particularly because of the focus on NTR. However, upon reading, I discovered that the book has several issues. The main character lacks agency, as events unfold around him without any proactive action on his part for the first 60 chapters.
A significant problem lies in his relationships with his girlfriend and best friend. They consistently belittle him openly, almost treating him like a bully's target. This constant disrespect makes the protagonist appear foolish, especially since he seems oblivious to it. If portrayed from the girlfriend's perspective, it could actually make for an intriguing story – a seemingly helpless victim repeatedly taken advantage of, yet still clinging to a toxic relationship.
In comparison, "Girlfriend Swap" (Koi Bi To Swap) handles this situation more effectively. The cheating girlfriend in that story genuinely cares for the protagonist, which adds depth to the drama and makes her actions more believable. Here, the lack of tension between the main character and his ex-partner feels unusual, as they show no concern for each other, which further complicates the narrative.
