Transmigration: Her Chosen Path

“She possessed the real daughter of the Orden family, Aria. However, this family already had a daughter, a fake daughter... Arin. Although she is a fake who took Aria's place all this time, Aria never thought of harassing her because she knew... she's not the real Arin but a transmigrator like herself who wants to be free not sold as a marriage. Knowing this and seeing the real person in front of her, Aria couldn't help but feel pity for her. They're both doomed to die in the original while they weren't even involved with the male lead of the novel. So, Aria decided to help her. However, coincidently she found out that Arin wasn't Arin but her twin Brother who went back in time?? He has been disguising himself this whole time as his sister to protect her from Aria's father's influence... Learning of his pain, she decided to return to his identity AND HELP HIM REGAIN HIS FREEDOM TO LIVE AS HIMSELF, not as his sister. While doing so, many secrets that had been buried will be uncovered, and... "Aria~" With a face full of tears and a longing expression, someone called me tenderly. This voice is so familiar... and this person's face too... Why is someone who doesn't belong here is here?”
