A dragon raised at birth

"Xiaolong, is my sister good-looking?"
The voice that was so gentle that the young dragon felt like its heart was warming rang in his ears, and the newly born young dragon stared dazedly at the gentle, dignified, holy, and peerless elder sister of the angel in front of him.
"nice."
Still not acclimated to the environment, the hatchling, whose head was dizzy and wanted to sleep, nodded ignorantly.
"Then you will follow your sister from now on, okay?"
"!?" Is there such a good thing?The dragonfly was no longer sleepy.
"Huh?" For a moment, the young dragon felt that the world in front of him had lost its color, and only the elder sister of the angel in front of him was shining with divine light.
"OK?"
"Okay." What is there to hesitate, the young dragon nodded heavily.
"Then sign this contract. After signing it, my sister will support you."
