With God's divine intervention, she met her ex-boyfriend that she left three years ago, Matthew Kim or widely known as B.M. It was worse enough when she found out that they went to the same college, even worse when he was the bestfriend of her bestfriend's boyfriend. As cold as she was, she can feel her heart being swayed by her drop dead gorgeous ex-boyfriend. Will he be able to melt her heart again? Will he be able to break through the fortress she built throughtout the years?
