The root of problem

For the first time, the root of Juheon's problem is revealed. Even right from the very beginning, Juheon has the tendecy of assuming everything on his own. From mistakenly believing Dohu had a crush on him, to believing Dohu would be fine without him, everything was all in Juheon's head. No matter how much Dohu tried to talk to him, nothing would go through if he already made up everything in his mind. The first step for this relationship to work is for Juheon to stop assuming things in regard to Dohu.
