The long lasting and always seen together in public couple Kim Joo Hyuk and Kim Ji Soo have broken up after a 6 year relationship. Kim Joo Hyuk and Kim Ji Soo had actually gone their separate ways in July of this year but the sad news was only announced today. They both belong to the same company, Namoo Actors, and have agreed to remain as friends. Namoo Actors said through a phone interview today, "The two did break up 3 months ago. They have kept the reason to themselves so we do not know why they broke up." It must be hard getting over someone you've been with for 6 years. I hope they find their happiness elsewhere soon.
