Fitch exclusive, Rina Otomi's first drama work! Rina, who is an underwear model in Tokyo, went home to celebrate her brother's birthday. Contrary to Rina's parents who are happy to return home, her younger brother Yuzuru has a deep-rooted personality who works for the game without welcoming him. He showed his underwear with a drunken momentum to his younger brother who was not interested in girls, and said, "You can touch it for a while ..." with half a joke, a word that awakened his younger brother's sleeping libido. From that day onward, my unequaled younger brother asks me to copulate all the time!
