Sisterzoned (Moonsun One-shot fanfic)

So I can't get a hang when Solar answered a question, "What is byul to you?" And she answered, "Sister".

On the other hand Moon byul answered, "soulmate".

Poor byul.

But since I am bored and still collecting ideas for my other ongoing stories I made this fanfic out of it. 😂

Hope you like it!
