Some things are better left unknown.

I must confess that I am starting to like you more and more each day,
but I've got no choice but to let go.
It's good that I don't know you that well, or else I would've been miserable by now.
Still, thank you for the good times, thank you for being amazing enough.
I just hope this feeling would go away soon.

You are definitely one of a kind.
