Best for: Readers who want a slow-burn drama with real consequences. The Gold Standard

The manga’s greatest strength is its rejection of the “reset button.” In lesser adult manga, a couple may experiment and return to normalcy. Here, once Miki experiences Kenji’s attentive, passionate style (contrasted with Tatsuya’s mechanical routine), she cannot un-feel that difference. Similarly, Tatsuya discovers Rina’s manipulative nature — and his own latent masochism. The narrative argues that some experiences create a before/after divide in a relationship that no amount of therapy or denial can bridge. Best for: Readers who want a slow-burn drama

As of April 2026, the manga is in its third major arc. Both couples have separated, and the story now follows their individual attempts at new relationships, therapy, or reconciliation. The author has stated in an interview that the ending will not be a “happy ending for everyone” but aims to be “honest about the cost of chasing desire.”

Given consistent sales (averaging 15,000+ copies per volume in Japan), a live-action drama adaptation was announced for late 2026.
