Passing Shower

(Rewriting with a new premise)

Lin Zhixia has a secret: her best friend is someone only she can see.

This "friend" of hers is rather strange.

He doesn't seem to like sunny days, and only ever hides beneath her little umbrella when it rains. He never tells her his name, only letting her call him "Xiao Shu." No matter how hard it rains, he never lets her walk him home.

They grew up together, and no matter how heavy the rain fell, "Xiao Shu" would never leave her. At least, that's what she believed until that day.

One day, Lin Zhixia opened her umbrella and looked around, feeling that something was wrong.

She realized that "Xiao Shu" seemed to have disappeared.
