Having an affair with his ex-lover after Minami Hatsukawa's wedding party

At my marriage party, unexpectedly my ex-girlfriend Minami Hatsukawa, who was also my first love, attended. I was quite surprised by that, but it didn't matter because everything was over. After the party, my wife left early because she was pregnant so she couldn't stay long, and I didn't understand why when I woke up I was in a hotel room, and then my ex-lover left. came and wanted to review old stories with me. I feel sorry for my wife about this, but her charm makes me irresistible.
