I guess this won't work out well even if he is now able to make sense of what he's bothering lately. Knowing his character and how he dealt with this, it's most likely he will just doing things that will cause rift in their relationship. Kim Dan and Jae Kyung only had give and take relationship, an unhealthy power imbalance where one benefited while the other is slowly drained away. It wasn't a nice feeling for someone who hasn't given emotional attainment for their sufferings when... all Kim Dan wants is for him to have someone who will be there for him and gave him what he truly deserves that I hardly see that in Jae Kyung since he's hard to understand.
