It’s a very beautiful drama everyone must watch it ,the direction ,the music ,acting ,plot everything was so superb. Lin Yi and Liu Haochun just acted so naturally and beautifully .The drama starts very beautifully with concept of time travel and then we come to know no thats nit it it was memory replacing thing and they were just dreaming .Though I would have preferred enter time travel plot over dream as I have seen similar thing in another drama ‘Legally Romance’ . But the drama was made really good with its turn and twists .Though the drama could have explore more on Xu Jinyang death plot but it didn’t .It was only thing I think can be done more . Nevertheless all the casts and leads did potray their characters perfectly .I would love to see them paired again in future.And at last drama did give meaning to the title of this drama ‘Derailment’ . It was always a pleasure to see that the title got its value .
