Xu Yin, born with a baby voice and deeply in love with her boyfriend Jiang Xu for three years, was repeatedly mocked and amused by him and his "female buddy" for it. When Xu Yin suffered a mudslide, broke her bone, and cried for help, Jiang Xu decided she was "acting for attention" and coldly turned off his phone. Completely heartbroken, Xu Yin decisively cut off the relationship, checked out and blocked him, and went alone to Europe to revive her career. Upon learning the truth, Jiang Xu fell apart in remorse, chased her to a foreign country to humbly kneel and beg for reconciliation, only to receive Xu Yin's cold rejection. In the end, Xu Yin shook off her insecurity, healed her wounds, and lived out a confident and poised heroine's life in the vast world.
