Synopsis: I Kissed My Girlfriend's Little Sister♥

As Haruka and I stood closely together, I whispered in her ear that we needed to be cautious about Shigure catching us in this situation. My heart rate increased as I realized that Haruka's twin sister was now my new stepsister, and their resemblance was uncanny. Haruka chuckled at my anxiousness, finding my nerves endearing. Today was a significant day in several respects. Not only had we reached the milestone of holding hands, but it was also the day that my dad remarried and brought Shigure into our family dynamic. But the similarity between Haruka and my stepsister made it difficult to control my thoughts. I felt guilty for being attracted to someone who was the spitting image of the person I loved. Shigure seemed to pick up on my discomfort and attempted to relieve my nerves. "It's okay, I understand. We look alike, right down to the...good stuff," she said with a smirk. The whole situation felt like a warped form of love, and I couldn't confide in Haruka about what was going on in my mind. All that mattered was that we didn't get caught by my stepsister.
