Heechul's Song for Orange Caramel, Meant for Hangeng?

I just recognise this, for real!

But the more I pay attention, the more it make sense

In the lyric, Heechul to Hangeng:

Hey there
Shanghai Boy who wear a suit
Why when i open my eyes
i dont see you
Without telling anything
You disappear you bad boy
Maybe you only love me for first time
I’m yours even if its only in dream

Even how much i miss you, it doesnt work
what should i do, what should i do
I guess i need to forget you
but how much i try, it doesnt work
You keeps appearing
I see you in my dream


Ooooooooo!!!

Haha, just sharing...

But this is definitely cute!
