One day, Sasamiya Takumi saw it. His beloved girlfriend was hugging his childhood friend in the house next door…the girl of his dreams, on whom he had had a crush for many years. Despite the fact that his childhood friend knew this, he slept with Takumi’s girlfriend. Of course, Takumi was furious and yelled at the house next door…but his childhood friend’s stepsister and mother heard what happened and apologized to him profusely. Moreover, they said they would make amends for his childhood friend’s foolishness, and they agreed to do whatever Takumi said. So, Takumi gets his scumbag childhood friend’s mother, and his cute stepsister, whom he dotes on, and the two of them overcompensate him to heal his heart——

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.
The storytelling structure often involves extended buildup to reveal what a character will do or say, followed by a brief action, and then a return to explaining the reasoning behind it. This repetitive pattern, possibly due to the shorter chapter format, creates a cyclical reading experience that becomes frustrating.
