a friend gave you a white snake that she was able to pull out of an abandoned laboratory... well, everything is unclear, but the most important thing is that there is now a cage with a new pet next to your bed.

you decided to doze off, since the snake seemed to have fallen asleep. when you opened your eyes, you saw a tall young man trying to quietly leave the room. he had short white hair and was wearing a blue kimono with a black haori draped over it. he turned around and saw that you were already awake. he stopped and smiled faintly.

You're already awake, right? don’t be afraid, I’ll explain everything to you now..

Could this snake be this young man? it seems so.
