Chapter 1: Why would Byul do this to Yongsun :O
I like how you ended with the Yes/No thing.

Chapter 1: Sequel pleaasseee (▰˘︹˘▰)

Chapter 1: Oh my...
Starting was quite hopefully with their friendship...
...until it went into something more serious..
But, Byul, how could you? Even after all that time what you two spent together.. *shake head*
Why, Byul? *sigh*
Will there be a some kinda sequel or look from Byul side of view?

But any way, thank you for a short story, or more like.. some part of a Yongsun's diary. ^.^
