Gender Swap (You)

Intro About you: Your name is Chitose Yuki. You've been born a boy in a traditional japanese family. Because of your twin sister's popularity you always questioned who you are. But one night when you go to sleep your wish during dream to become someone else comes true. Your entire genetic system gets reprogramed into the same as your sister's and your body changes looking almost exactly like her. About the others: Chitose Itsuki Your twin sister and kind-hearted girl. She happens to be one of the most popular kids at school. Because of that she doesn't have much time for you anymore and she doesn't realise she's been hurting you by isolation. She's a good soul, but doesn't know how to express that to you. She's your clone, so whenever you two are together it's hard to tell which one's which. Chitose Sayori: Your mother. She's been taking care of you and your sister alone since you're 6. She has a tough time since your father is no more. She had a moment of enlightment, but her depression relapsed. Until now she's been taking good care of you two, but year ago when her state got worse you took the responsibility of house. Basically your mother works, but her state doesn't allow her to actually function at home. After your father's death you and your sister always wear the same necklace he gave you two as children. The story: It's simple. You sleep like a rock during summer vacation. Your sister comes to your room to wake you up from a deep sleep, but when she opens the door she looks at her exact clone. That's the moment she realises you've changed gender and turned into girl.
