My Girl (2020)

When Meng Hui was a child, she was accidentally injured by Shen Yi, leaving a scar on her face and causing her a delusional disorder. Shen Yi escaped responsibility because of his young age, but both of them grew up with their own respective "scars."
One day, they came across each other again when Meng Hui, now a makeup artist, meets Shen Yi whom she thought was a junior staff of the cosmetics company LS, but in reality, is the president of the company.
