Extra 1. The Jade-Blue Eyes

My name is Wu Lan Yu. I was born an orphan. According to what Aunt Diana told me, that's true. I had a mother who loved me very much, but I never knew her face. I had an older brother; he was the one who loved me most in the world, but he could never be by my side for a full day.
When I was seven, that was the first time I understood why I was born into this world. My friends and I were taken to SIC, a training center for omnipotent assassins serving national interests. At that time, I was very scared; I didn't want to be in this place. They always bullied me, hit me. I was so scared. I really wanted my older brother by my side. I didn't want to be here.
On the first day of training, I immediately escaped from the base. I ran all the way to a nearby beach. I just sat there and cried, cried endlessly...
"Huhuhu... Brother, I'm so scared... huhu... Brother..."
"What's wrong?"
Then suddenly, someone appeared from behind, startling me. My crying grew louder, and that person seemed a little flustered, not knowing what to do to comfort me. He just sat there looking at me, his hands clean like my brother's, gently stroking my head.
"Don't cry, who bullied you?"
He smiled at me, his innocent face very adorable, making me no longer want to cry.
"They bullied me, didn't let me eat..."
I rubbed my eyes slightly, my face smudged with dirt and tears, making him burst into laughter, an action that made me want to cry even more.
"I'm not laughing at you, don't cry, don't cry. And little one, what's your name?"
He asked me.
"My name is Wu Lan Yu."
I replied happily, and he, as if he had found something interesting about me, his dark eyes curved.
"Lan Yu, jade-blue, is that the color of your eyes? Your eyes are jade-blue, very beautiful..."
He cheered.
"Yes, Aunt Diana said so too. Jade-blue is the color of my eyes, and my brother also said so."
I smiled faintly, revealing a missing tooth, which made him laugh again, but he tried to suppress it when he saw my face, which looked like it was about to cry.
"I am Huang Hai Lang, which means 'calm sea.' From now on, I will definitely protect you, Lan Yu."
He smiled and lightly kissed my cheek. After that day, every time training was over, I would run to this place to find him, but not long after, he said he had to leave. At that time, I cried a lot. I didn't want him to go, but it seemed too difficult.
"Don't cry. I will definitely come find you later, I will protect you, okay?"
He stroked my messy head and said.
"Then, when that time comes, I'll make you happy, okay? Aunt Diana said we should make the people we love happy."
I replied innocently, but only saw him burst into laughter. In his chubby hand, he took out a very beautiful angel wing necklace and put it around my neck.
"Okay, until then, don't lose it."
He smiled faintly, then disappeared into the forest, and never returned.
I waited for him to return for fourteen years, but in the end, he still didn't come for me. He forgot me, forgot his promise to protect me. Only I kept my promise, the promise to make him happy.
