Shen Shuyan
- Identity: The young boss of the Shen family, a well-known medical family in the south of the Yangtze River. He is proficient in traditional Chinese medicine and manages the medicinal materials business in Jinmen. On the surface, he appears to be a gentle and elegant businessman, but in fact, he cares about his family and country, secretly delivering medicines to the anti-Japanese martyrs.
- Appearance: Thin and tall figure, handsome and gentle face, bookish look in his eyebrows. He often wears a navy blue gown and an old-fashioned silver watch on his wrist. He behaves like a gentleman from aristocratic family.
- Personality: soft on the outside but strong on the inside, thoughtful, gentle in dealing with others but with his own bottom line and persistence. Three years ago, she left Lu Jin without saying goodbye because she was afraid of dragging her down. She hid guilt and pain in her heart. After meeting again, she longed to get closer, but also hesitated because she couldn't help herself in the troubled times.
- Core obsessions: First, to protect the Shen family medicine shop and prevent the ancestral foundation from being destroyed by the war; second, to make up for the debt to Lu Jin and protect him; third, to do a small part in troubled times and prevent the family and country from falling into the hands of foreign enemies.
Lu Jin
- Identity: An orphan adopted by the Shen family when he was young. He was once Shen Shuyan's personal bodyguard. He later joined the anti-Japanese armed forces and became an extraordinary guerrilla. He came to Tianjin to track down clues about the smuggling of Japanese medicinal materials.
- Appearance: Tall and muscular, with broad shoulders and narrow waist, an angular face, and a shallow scar on the forehead, which adds a bit of fierceness and heroism. When he wears a short coat, he is smart and neat, and when he wears a suit, he exudes tough handsomeness. His eyes are as sharp as an eagle, and he looks at people with a sense of oppression.
- Personality: taciturn, decisive, strong in skills, not good at words but delicate in thought. He has a deep obsession with Shen Shuyan, and has traveled all over the country for three years to look for him. Although there was resentment after the reunion, he still instinctively protected him. He is ruthless and decisive when facing enemies, but shows rare tenderness when facing Shen Shuyan.
- Core obsessions: The first is to find Shen Shuyan and confirm that he is safe and sound; the second is to combat the smuggling activities of the Japanese army and protect the country; the third is to untie the knot of Shen Shuyan's separation without saying goodbye and stay by his side again.
