he still struggles with losing her, he has faced it a few times through a friend who sorta made him comfortable enough to talk about her. ujin would have totally took good care of him, they developed a close friendship, he taught him some korean (family still spoke korean), mainly the bad words ;) lets face it ujin isn't the best influence at times. even after wonjae left they still could have kept on touch and reconnected once he moved into skyview.
