Mr. Fu, I Don't Want to Be My Sister's Substitute Anymore.

"Do you like me so much? Do you like me enough to kill your own sister?" "In that case, I will let you have your wish! From today on, you are her!" She wants to escape, but there is no way to retreat. She wants to explain, but she is unable to do so. When all her wings are broken, her freedom is imprisoned. My heart is also dead. If there is an afterlife, we will never see each other again!
