Until she stood outside the wedding venue where he was about to marry another woman.

Her heart was dead. Nothing was worth holding back anymore.

She wanted to escape, but she was unwilling to let him live the rest of his life peacefully.

Hence, under the reporters’ flashing lights, she stepped onto the bridge and jumped off with her nearly due baby…
