I... Just don't want to care, okay?
Why do you want to imprison me?
Even if I am your sister.
But I won't change for you....
I like Ren, I just like Ren, and I am very happy with Ren...
I want to be with Ren, why should you stop me...
I don't care about anyone or anything, nothing can stop me from liking Ren and being with Ren. I just want to be with Ren....
