There is still a tad of romance in here, it can't be helped. I couldn't enjoy another romance drama because Hidden Love set the bar so high. Found this and thought it would be the perfect palette cleanser. I was worried about how they were going to drag the story into 15 episodes, but after episode 8, I couldn't stop watching and had to finish the rest of the episodes in one sitting. The most frustrating moments for me were the time the police spent interrogating them. Also, they showed the backstory of most of the passengers but not much about He Yun and Shi Qing. I guess one is a game designer, and the other is a college student but what else ? I enjoyed this overall.
