The reps from both of their agencies stated, "They have been dating since this past June... It is hard to comment [on marriage plans] because no one knows what will happen and it is their private matter... However, the two of them, who are both at the age for marriage, are not dating lightheartedly." 

The couple went from playing a married couple on 'A Hundred Year's Inheritance' to a real-life couple this past June. Choi Won Young recently starred in 'Heirs' and Shim Yi Young also starred in another hit drama 'You Who Rolled In Unexpectedly' and most recently, 'Suspicious Housekeeper'.
