What is happening to me?

I was saved by this little girl,

Even though I refused her help,

She continued anyway.

Later I found her dead, I felt strange,

So I revived her with my Tessaiga.

I have never felt the same,

Later she died again,

And my mother put aside her hatred of humans and brought her back,

What made her change?

I have been denying to myself that I like rin,

But did my mother want me to be happy?

Did she see that I care for this girl?
