He’d never agree to break their bond now!Well then… What else could a guy do but to run away?But fate wasn’t done dealing with him.Soon after he left, he discovered he was pregnant! From then on, he not only would have to worry about his own survival, but also take care of a child!Two months later, after traveling across the country, he finally found a nice town to settle in.
