An illusion called love - Sosuke Aizen
She believed she had found in Aizen someone capable of understanding her like no one else. Aizen disappeared without saying goodbye, leaving her with nothing but the memory of a corpse. Years later, with Aizen imprisoned in Muken and her engaged to Byakuya out of familial duty, their paths cross once again. Amid secrets, unspoken feelings, and a question that has never stopped haunting her, they will be forced to confront an uncomfortable truth: perhaps the only person Aizen chose to lose was also the only person he ever truly wanted to keep.
