One day, on a paper of a diary he bought, of course with Xin's money, he was writing something. That something was a letter about what he would say to his family:

What would I say to...:

Dad: I hate you the most, you thought only about your stupid France and not about me. If I had the chance to save you, I wouldn't.

Mom: You... You too, but you at least did something if I was bad, even if it was only because I was the prince. But the one thing that broke my heart was the day when I went home bleeding and dying because I fought and you just gave me chamomile.

Brother: I love you, brother, you were the only one I cared about and who cared about me. You could hug me if I was sad or more, you will be in my heart forever, I hope you will become a spirit and I will meet you once again...

Margot, the cat: Love you so much, my fluffy creature. I want to pet you.

After that letter he just left it on the table. Then he just went to school. Xin was at home because he was one year older than Shuro, so he finished school one year earlier than him. Xin just saw the letter and, as someone who was always interested, he read it. Then he understood the real reality... He understood why Shuro wasn't really open, yeah, the first times he learned the language he didn't try to talk with Xin.
