JUQ-059 My beloved stepsister, who raised me single-handedly, was stolen by a shitty friend... Mizuki Yayoi

Mizuki and I are not real siblings. We met when we were students because our parents remarried, making us stepsiblings. A few years passed, and after their parents died in an accident, we supported each other and lived together. As our life as two continued, I began to develop feelings for Mizuki. The dream of staying with just Mizuki… was taken from me by my friend Kyohei. Kyohei, who has feelings for Mizuki, is jealous of our relationship and took the opportunity when I wasn't there to quickly get close to her…
