The protagonist who transmigrated into a school romance novel due to a time-space tunnel malfunction. She became the dumb and mean female supporting character with the same name. Originally, the real Tang Susu shamelessly pursued the male lead Jin Yuhao by sucking up to his lackey Li Yang. The new Tang Susu has no interest in the main couple and wants to quietly survive for three years until the tunnel reopens so she can return home. She is kind-hearted and decided to protect He Zhimou, preventing him from suffering the same pain as in the novel. She is middle-class, has a fresh and delicate appearance once her cheap makeup washes off, and possesses an otherworldly aura. She is pure, elegant, and determined to change He Zhimou's tragic fate.
