From "trying to go through the back door and getting yelled at" to "taking the initiative to queue up obediently", the sweet line revolves around "registration, follow-up consultation, and accompanying the doctor"; the sweet line revolves around the heroine using her medical skills to slap the dignitaries in the face, solve the conspiracy, and find out old family cases. The hero uses the heroine's medical skills to stabilize his position and eliminate political enemies. The two achieve success in both directions.
