Don't hate Juheon, he has his reasons. It was hard for him to feel like he was used again by the person he opened his heart to. It's hard to break the barrier of showing yourself vulnerable to others when the people only see you superficially. Also, the main reason Juheon disdained him is because his aunt blackmailed him into doing something to Dohu if he didn't obey her in everything.
