The Quarter-Beauty of the Class Became My Stepsister. I Had Been Unknowingly Flirting With Her (LN)

Nanase Chloe, a beautiful quarter-blooded girl who is out of reach. She was supposed to be far from me, but our parents remarried and we became siblings!? We suddenly started living together. I was friendly with her because we were from a peaceful family, but she was strangely embarrassed by my every word. I complimented her on her cooking, told her she didn’t need to rush to get closer, and said, “We’ll be together forever, so it’s okay, but…” and told her we should live happily as a family. “Let’s be happy together, isn’t that a proposal?” I was wooing her without even realizing it!? “I’m no good, but please…” Under the same roof, an unconscious love comedy begins!
