as much as that's a reason he ran away it doesn't justify how shi*** he made it for Joo. He was aware of Joo's feelings and despite that, continuously ignored that fact and acted as if Joo hadn't been putting in all the effort up to that point. Joo initiated most if not all interacts between the two of them and Jinwook reciprocated none of it till it had some benefits on his end. In terms of Jiwook running away, he may have had a reason but he didn't even try to confide in Joo, and even dejected Joo when he tried to open up and be more honest and vulnerable about himself. Joo gave up his pride for Jiwook, and Jiwook couldn't even be a decent person for Joo.
