**Protagonist: Su Wan** - 25 years old, resident doctor in cardiac surgery. With a beautiful and refined appearance, a clean and gentle temperament, a kind and tough personality, and a slightly bookish temperament, he is a typical "other people's child". Good tutoring and simple emotional experience.
* **Male protagonist: Chen Mo** - 33 years old. A top executive comes from a family (grandfather/father has a prominent position) and has a profound background. I am a successful businessman (in the field of technology/investment) with strong skills, a bit of ruffianism and unruly style of conduct, a strong aura, and avoid approaching strangers. I am especially cold to women who take the initiative to approach me. I am nicknamed "Chen Fozi" in the circle (meaning pure-hearted and celibate). But after meeting Su Wan, the iceberg melted. He was very possessive and doted on his wife to no great extent.
