Everyone had a long day. Park Duri expected Ro Kyung to not follow them after all the gunshots and blood. But his best friend did not hesitate to follow along.
Park Duri noticed Ro Kyung's eyes glued to Min Jun as if he was trying to figure out many things. It was known to everyone Ro Kyung was the oblivious one, but he was observant too. A good one that when he put his mind to one, he could figure out anything. He had been observing Min Jun for a long time as if he was trying to figure out something.
Gok Cho Kija also followed them despite puking his gut out after witnessing everything. He was repulsed by everything that happened, especially the one that happened in the restroom. Irrespective of being part of the mafia family, he was never engaged in anything brutal. So he was taken by surprise, and his stomach became weak.
Look at people bullying Young Jae, and the innocent tokki did not even realise how evident his feeling for Min Jun was to everyone!
