One has been hurt too deeply to care for love; the other fell at first sight and could never forget for years.
One thought he was being open and honest, following his heart; the other hid his feelings and lured him in step by step.
One came to his senses too late and turned the tables; the other sank ever deeper, and loved every minute of it.
As they circled around each other, two lines that should have crossed and then gone their separate ways took a turn at a certain point. From then on, they wound around each other, knotting themselves together until they could never be parted.
