CEO au

Once, you and Giyuu were just unemployed and poor siblings, but you stayed together, until someone took Giyuu from you, separating you for years. You always cried, and it emptied your mind, making you forget who Giyuu was to you. Meanwhile, Giyuu was adopted by a CEO's family. After several years, Giyuu became a famous CEO businessman and you became a flower shop owner.
