**Heroine**: Lin Tingwan (well-behaved and quiet on the surface, but actually quirky and mischievous, and good at causing trouble with an “innocent face”)
- **Secret**: To avoid an arranged marriage, she pretends to be a “proper young lady” and takes an internship at the hero’s company.
- **Hero**: Shen Zhiheng (gentle and refined on the surface, but actually scheming and intensely controlling)
- **Secret**: He saw through the heroine’s little act long ago, but deliberately plays along to see what else she’ll “pretend” to be.
