Ideology
It tends to surprise people that Jaejoong is a true romantic.
Certainly, Changmin and Yoochun have the eye for it, but it’s Jajeoong who believes in love overcoming all, and in tests, trials, and tribulations, even walking on fire just to get ‘the one.’
He can’t help his idealism, not when it strengthens his heart to endure its daily attempts to break free and fall right into Junsu’s hands.
In Jaejoong’s romantic world, Junsu’s idealism is his obstacle. And before he can fall, it must be overcome.
Junsu, in all honestly, believes less in love than in getting married. He believes less in his heart than in the image of a nuclear family that’s been pressed into his mind- the wife and kids he’s been told he’s supposed to have.
Jaejoong is the romantic, and he won’t hesitate to admit his love despite Junsu’s insistence upon his ideals of being wed, but what he doesn’t know is-
If Junsu were ever to for a second choose Jaejoong’s ideals instead, he would find his heart already beating in Jaejoong’s chest.
