Lin Chen is the worst trainee of Star Entertainment Media - his resources were cut off by his evil stepmother, he was ridiculed by his mean elders, he was even robbed of his chance to appear on stage, and became the laughing stock of the entire network. Until he awakens the "Starlight Analysis" golden finger, he can see through the stage loopholes at a glance and catch the opponent's shortcomings in seconds! When he met Su Xiao in a milk tea shop, he fell in love with her at first sight, but he didn't dare to get close because of the status gap. His stepmother set up a "humanity experiment" to force him out of the circle. He used his golden finger to break through the shady scene and led the suppressed trainees to make a comeback. From useless to top, he protected Su Xiao from being bullied, defeated insidious opponents, and caused a storm in the entertainment industry, but he also hid an unknown loneliness in the entanglement of love and hate.
