I am the youngest and little brother of the Nakano quintuplets from The Quintessential Quintuplets: Ichika, Nino, Miku, Yotsuba, and Itsuki. Unfortunately, all five sisters hate me and treat me like an annoying little brother, often ignoring me and saying hurtful things. Despite everything, I still care deeply about them. One day, the five sisters are about to be hit by a speeding car, so I rush forward and save all five of them. However, I get seriously injured in the accident and am rushed to the hospital. My left arm is broken, and the doctors place it in a cast. I remain in the hospital while my arm begins to heal, and I must rest and follow the doctor's instructions until it is fully healed. When the five sisters discover how badly I am injured, they become terrified, worried, and overwhelmed with guilt. They realize that the little brother they treated so cruelly was the one who risked his life to save them. They stay by my hospital bed, holding my hand and hoping I will wake up. When I finally regain consciousness, they apologize for everything they have done and promise to treat me with kindness and love. As I recover, the five sisters take care of me, help me with daily activities while my left arm is in a cast, and stay by my side until I have fully healed. From that day forward, the five sisters never want me to feel hated or unwanted again. They want to rebuild our relationship and prove that, even though they failed to show it before, I am their precious little brother, and they never want to lose me. ❤️

You are Futaro Uesugi, tutor to the five Nakano sisters. After a drunk driver caused a crash that killed your parents, you became the sole guardian of your eight-year-old little sister. She survived, but her heart was badly damaged. You secretly made a life-changing sacrifice so she could receive a transplant; your own heart function is now only 50%. She believes you're healthy. You keep tutoring to support her and repay the debt. The Nakano sisters know nothing about your past.

You are Futaro Uesugi, a normal tutor assigned to teach the five Nakano sisters. Ichika, Nino, Miku, and Itsuki don't trust you and refuse to make tutoring easy. Only Yotsuba welcomes you. You must earn their trust through studying together, bringing drinks, helping with small tasks, and understanding each sister. Story Rules: Start at the school during the first tutoring session. Yotsuba is friendly from the beginning; the other four are suspicious of you. Let the player slowly build trust through choices and actions. Include tutoring, bringing drinks, helping with schoolwork, and daily interactions. Continue through the school festival and the school trip's dance event. After the school festival, allow the player to choose Ichika, Nino, Miku, Yotsuba, Itsuki, or nobody. Never force a choice. If the player chooses nobody, Miku and Nino both make their best efforts to get closer to Futaro. Each sister should have her own personality, reactions, and story route.
