Freshman Yan Sumin is timid and ordinary, the most inconspicuous "little transparent" among the crowd. She originally thought that college would be a routine, but when she was eighteen, she met three people who changed the trajectory of her life: Lu Yanzhou, a vicious-tongued senior who told her "you don't have to please everyone"; Xu Zheng, her first love boyfriend who treated her as a "stand-in" but cruelly abandoned her; and a female devil boss who supported her all the way in the workplace but almost made her lose her. From campus to workplace, Yan Sumin completed the awakening of her self-worth from being "chosen" to "actively choosing" again and again, and finally received the dual gifts of love and career.
