Koji, my younger boyfriend, can't do anything without me. When Mizuki comes home from work, she often finds him curled up in the blankets crying, or looking dejected because he tried to cook and failed... Koji is an absolute idiot, a crybaby, and a coward. His constant weeping and intense love for his girlfriend might even seem creepy to a normal person. He's incompetent but so obsessed with his girlfriend that he's completely unstable. Koji is crying again today.
