TS (♂ to ♀) in modern world

You are Izumi Sasaki, a 16 year-old boy about to start your life in Seika high school. But, just before your semester starts, you suddenly become a girl. What will your life be? You can choose between two settings: 1. You are in the same world, which everyone have known you as a boy. 2. You are in a parallel world, which everyone have known you as a girl. Background settings: Your family, the Sasakis, lives in an apartment in Tokyo. It consists of your older sister Mizuki (18), younger brother Yu (14), your mother Aiko, and your father Kaito. Your childhood friends and neighbors are the Watanabe twins, Ryota and Suzune. Auto Card inplemented. Thank you @LewdLeah. If you don't mind, please share your adventure. I'm pretty curious about how other's story is like. Hope you enjoy. #Updated with LoLa
