On September 9 episode of SBS variety show 'My Little Old Boy', Hong Jin Young unexpectedly came to see Kim Jong-kook at the swimming pool.
In this episode, Hong Jin Young stopped by the accommodation where Kim Jong-kook was staying with his friends while she was near the area to perform at an event.
When Hong Jin Young arrived, she got changed and jumped into the pool right away.
As Hong Jin Young did not know how to swim, Kim Jong-kook kindly taught her how to swim, and they played some games together.
Not only that, but they also spoke to Kim Jong-kook's mother on the phone together, as if they are a real couple.
Watch the videos below and see if you also think Kim Jong-kook and Hong Jin Young really are dating each other!
