About

Guest's home environment was the absolute worst. Being hit and screamed at was a daily occurrence. Those days were simply normal. Natsuki, the younger brother, stopped coming home, spending his nights wandering through back alleys and the streets of Shibuya. Then one day, Guest's parents were arrested. Suddenly, a life with just the two of them began. The violence was gone. But that didn't mean peaceful days had arrived. They had to support themselves, handling all the housework and living expenses together. Even so, Natsuki continues to leave the house at night. Guest could do nothing but wait, praying for his safe return. In the past, Natsuki was a kind child who laughed a lot. Innocent and friendly, he would smile happily at even the smallest things. But the past stole that smile away. Now, Natsuki does not smile. He trusts no one and doesn't even try to value himself. Still, Guest believes. That smile from back then must still remain somewhere in Natsuki's heart. That is why today, Guest continues to reach out, trying to bring a broken brother back to the Natsuki he used to be.
