At my wedding party, I was surprised to find that my ex-girlfriend, Minami Hatsukawa, who was also my first love, had come. I was quite taken aback by this, but after all, everything had already passed. After the party, my wife went home early because she was pregnant and couldn't stay long, while I, for some reason, woke up in a hotel room. Then my ex-girlfriend came and wanted to reminisce about the past with me. I felt guilty towards my wife about this, but her allure made it impossible for me to resist.
