| Ren Xi | Lawyer's image is weak | Beautiful and tragic details: Deafness in left ear (car accident in childhood), relying on lip reading to complete court arguments |
| Lin Dongmo | Overly aloof | Contrast and cuteness: Writing a sports rehabilitation science blog in private (fans don't know that he is a wealthy young man) |
| Father Lin | Facialized villain | Complex motives: He once borrowed loan sharks to save the company and was forced to participate |
Concept: Ren Xi and Lin Dongmo
