However everyone doesn't believe that since his appearance and personality isn't similar to hers. Hiroto is also the outcast in his own family, for many reasons that only him and his parents know. Being outcasted made him lose hope for gaining anyone to care and love for. So he decided to live only for himself and his lover. Then one day, he disappeared or more specifically, he left. Only to come back as someone very different. What happened to him?
