Kazoku ga Ai Oshikute Rikon Dekimasen

After being transported into the world of a novel as a completely ordinary supporting character, I intended to live a quiet life. Yet, swept along by circumstances, I ended up marrying the heroine's father. My plan was simple: make the daughter happy, then divorce. That was all it was meant to be. But the daughter was utterly endearing, and her husband—though clumsy—was gentle at heart. Little by little, smiles began to fill their once-cold home, and my resolve to pursue a divorce started to waver as I found myself genuinely wanting to stay. Despite the misunderstandings of those around us, the complications of family, and the looming "separation route" laid out in the original story, the three of us slowly reclaim the warmth of home through the small, everyday choices we make together.
