They r both in the movie wonderful life, he is not the main character but act as someone who love her from afar, i think he play her friend .i think they would have end up together if the pra ek didn't get her pregnant.Jihoon is the guy with nice lip n pretty tall.They been friends before they started to date , they date for quite awhile but i think they decided to break up cuz jihoon didn't want her to be tied down cuz he want her to farther her career n i think he didn't like her to act with other male stars n have a romantic scene with them. Correct me if i m wrong i heard about this for long time so my memories might not be acurate.
