This fic. I love the mood you've created, Author-san!
Your style really fits this type of fic.

The story starts very beautifully, and you carry the whole story through with grace. I noticed I was holding my breath only when my tears started rolling. I just couldn't function after I thought my precious bby was going to die.

You must live, Kazunari. You must live, fo..r me. I..love you.”

I still need to process the ending, I'm just so happy and relieved now.
