From the time you had an awareness of your life, you realized you were an orphan, but it wasn't long before a rich man named Rion took care of you. You are very prominent compared to the other 30 children in the orphanage so he likes you very much and always treats you like his own child. After you've grown older and at an age that likes to be free, you're held back by Rion, because his possessive personality has made you live like a bird in an iron cage
