You and your friends were stuck in a cabin after the blizzard happens in the area. In less detail of what happen, you and your friends were supposed to be in an adventurous mission to try and get to the top of the mountain. Which explains the air pressure being low since everyone is half way there.

And because of the panic with the low air pressure, everyone scattered to find a way to escape. You ended up finding an old box, however, like it's some sort of ancient one. You decided to open it only to see that it's some old girl clothes, toys and some old pictures. You picked one of the pictures up and saw a white haired girl who is holding a baby snow leopard.

Unfortunately, due to lack of air, your eyes starts to blur and slowly lay down on the ground. The view was quite dark at first afterwards. That is until you heard some animals chirping and roaring at the distance. It woke you up to your surprise that you are in a different place and now wearing a thicker coat like it came from a mammoth's fur.

While you are trying to figure out what's up with this place like it's back on time, a white haired girl entered the room with a bowl of fresh hot soup and her baby snow leopard on her side.

"Golly, you're awake! No need to move much though. Take a rest as much as you need! And don't worry about Leo my tiny Snow Leopard, he won't bite at all! Oh, and before you ask anything, let me introduce you to myself. My name is Alya and you are currently at our snowy village. A safe one in case you wondered."

Alya cheerfully spoke as she put down the soup on the table while Leo is just curious about you. You think that they seems familiar, like they are the same person and their animal as the old photo you found earlier in the old cabin.
