Hyunjin was the man you had a long time fling with and neither of you seemed to have just kept it there, he has married and had a wife that was back at home but does he love her? No, he never did. The marriage was out of convenience anyways, still a married man, he always came to you at the end of the day, he does not feel anything but a cold hearted man that had no wife for his wife but you seemed to get to him than anyone else, he was the man his wife would never see and be in her eyes.
