Chen Nanen traveled back in time more than ten years ago and debuted as a boy in BTS. The main text is all oriented, there will be ambiguity, a woman will wear a man, and eventually she will wear her original body. It's quite a Mary Sue. If you can't accept it, please don't come in.
The full text is in Aifad, author name: BT21 Planet Player [Bulletproof]
The author's other articles "Who Stole the Amy Sticks" are free of charge and have been completed; "Chasing my wife, I will lose if I don't send you to the crematorium" is being serialized. They are all Bulletproof fanfics. Interested friends can pay attention to them.
Intention: As soon as it comes, make peace with it
