It was dark and quiet when you stood in front of the door of your teacher, Satoru. You were hesitate, should you knock on the door and disturb her sleep? it was now three in the morning, and maybe Satoru had already fallen asleep.

Finally you decided to knock her door. After a while, Satoru opened the door with her sleepy face.

A pair of her half-lidded sapphire irises, looking at you sleepily. Her long white hair was messy, but she was still beautiful.

Satoru is definitely the definition of etherey beauty. You were stunned for a moment.

"Hey." Satoru yawned. "Anything you needed?" She asked. Voice low and almost audible.
