The Great Mad Dog

My first love came back, with my fiancé. "Long time no see, pretty girl?" Do-kyung, her first love, suddenly appeared before Yu-Ju, who was about to get married. It had been nine years. They had broken up when she was twenty, and when she met him at twenty-nine, he was still handsome, strong, and a mad dog. "Just know this. I just bet everything I have on breaking off your engagement." Yu-Ju tried to push Do-Kyung away, who had come to ruin her life again. Do-Kyung was incomprehensibly desperate for Yu-Ju."Yu-Ju. How far would you go for the person you love? I would be a mad dog for you, willingly."(Source: KakaoPage, translated)
