Hua Ji Yinyin, recognized as a cool person at Xinghai University, has a temperament like the moon, but she is a "idiot beauty" with a nine-level disability in life - a top-notch fool, lack of common sense, and strange thinking. The second generation of the dandy, Jiang Wei, hides a fatal weakness under his arrogant and domineering appearance: a severe fear of heights. Once when he got lost and crashed, she calmly pointed out that he had parked illegally, and her logic was so clear that he was speechless. After being forced to be tied up, he became her "human navigator", despising her words but taking honest actions to clean up the trouble she caused; she was the only "safety rope" he could rely on when he was afraid of heights, giving him calming strength with his unique cuteness. From disapproval of each other to guarding the integrity of the body with verbal disapproval, to trembling confessions in high-altitude crises, the contrasting cute CPs collided with countless ironic and heart-warming sparks. When the sun, which is afraid of heights, meets the lost moon, they become each other's most unexpected and indispensable antidote.
