Summer Sister

So Naoko received a letter from Okinawa. The letterer, Omura Tsuruo, claimed that he might be her half-brother. So Naoko came to Okinawa with her father's fiancée Momoko, hoping to take the opportunity to find her brother. However, Tsuruo once met Taozi and regarded her as his younger sister, but he had no feelings for Sonaoko. Taozi betrayed her fiancé and fell in love with Henan. Sonaoko accidentally met Kuniyoshi, who may also be Omura Tsurao's father. Kuniyoshi and Sonaoko's father, Kikuchi, were college classmates, and Tsurao didn't know whose child they were. Kuniyoshi and Kikuchi, who were once antagonistic back then, are now high-ranking dignitaries in Okinawa and Tokyo. It should be their most appropriate attitude to laugh off these past entanglements. The relationship between Okinawa and Japan is metaphorically reflected in this blood story.
