The core of the TV drama "Derailment" lies in the remarkable transformation of the protagonist, Jiang Xiao Yuan. She transitions from a privileged heiress, lacking nothing, to a young girl struggling in her daily life. This transformation should have been the climax of the plot, filled with internal turmoil and struggles. However, from the audience's perspective, this change is handled too swiftly, as if Jiang Xiao Yuan effortlessly adapts to her new lifestyle. Such treatment greatly diminishes the authenticity and impact of the storyline.

In "Derailment," the character Qi Lian shines like a radiant beam of light, leaving a profound impression on the audience. His love for Jiang Xiao Yuan remains unwavering, regardless of any changes in their social status. Qi Lian is not only an affectionate male lead, but his righteousness and kindness make him the most attractive character in the drama. His understanding and support for Jiang Xiao Yuan demonstrate a mature and inclusive perspective on love.

These qualities make Qi Lian stand out prominently in the plot. His love is not only a source of support for Jiang Xiao Yuan but also provides her with a solid foundation during her identity transformation. It is because of Qi Lian's presence that Jiang Xiao Yuan's story becomes more vivid and moving. However, just as the audience becomes increasingly interested in this brave and righteous male lead, the plot leaves behind some mysteries surrounding him.

For instance, the relationship between Jiang Xiao Yuan and Qi Lian sometimes abruptly shifts focus to other supporting characters. These transitions are not smooth or conducive to the main storyline's development. This not only confuses the audience but also diminishes their interest in the main plot. To improve this aspect, the arrangement of the series needs to pay more attention to logical coherence and the tight integration of the plot.

In this drama, the actors' performances undoubtedly serve as the highlight, especially those portraying Jiang Xiao Yuan and Qi Lian. Liu Hao Cun, who plays Jiang Xiao Yuan, perfectly depicts the emotional fluctuations during her transition from a wealthy heiress to a working-class girl through nuanced acting. Her performance vividly showcases Jiang Xiao Yuan's confusion, struggles in the face of life's challenges, and her gradual adaptation and growth in the new environment. This distinct portrayal allows the audience to deeply sense the character's genuine emotions and generate a strong resonance.

Similarly, Lin Yi, who portrays Qi Lian, successfully shapes a character that is both brave and just, yet tender and delicate, through his deep and determined gaze and actions. His love for Jiang Xiao Yuan and his unwavering loyalty after her identity transformation add a warm and intense emotional drive to the series. His performance not only makes Qi Lian a major highlight in the drama but also enhances the overall liveliness and poignancy of the plot. The outstanding performances of these two leads not only elevate the artistic quality of the entire series but also become a topic of extensive discussion. Their acting skills enrich the characters' emotions, making the audience not only focus on the plot's development but also experience the characters' inner journeys while watching the drama.
