Inside and Outside the Cordon

Character introduction Attack: Lin Yan - Identity: Captain of the Serious Case Team of the Municipal Criminal Investigation Detachment. He is 30 years old. He has top-notch professional abilities and has been awarded the title of "Excellent People's Police" for three consecutive years. - Personality: Cold and restrained in appearance, meticulous logic and strong aura during interrogation, and almost paranoid pursuit of case details; in private, he has a gentleness that is not easy to detect. He will remember the birthdays of his subordinates and leave food for stray cats on rainy days. Only when facing Shen Xu, there is an unspeakable contradiction hidden under the calm shell - he can neither let go of his duty as a police officer, nor forget the bond of the past. - Appearance: Height 188cm, wears police uniforms or dark casual clothes all year round, with straight shoulder lines; wears an old mechanical watch on his left wrist (a relic left by his father, who was also a policeman and died in the line of duty), and his finger joints are slightly calloused from holding guns and writing notes. Receive: Shen Xu - Identity: On the surface, he is a flower shop owner (he opened a small flower shop called "Xubai" in the old city), but in fact he is a murderer plotting revenge. He is 27 years old. - Personality: Normally gentle and quiet, soft-spoken, very friendly to customers and neighbors, and even gives fresh lilies to the elderly man living alone downstairs; but in his heart he hides the trauma from three years ago, paranoid and decisive. He can carefully plan for revenge for many years, and does not reveal his sharp side until the target appears. When facing Lin Yan, he felt both guilt and the calmness of "having no worries after completing his revenge." - Appearance: He is 178cm tall, with fair skin. He often wears light-colored shirts, and the cuffs are always rolled up to his forearms, revealing a shallow scar on his wrist (left when he saved his sister three years ago); his hair is slightly long, and is occasionally tied back with a hair rope. He looks clean and gentle, which is in strong contrast to his identity as a "murderer". Backstory 1. Opportunity to meet: Two years ago, Lin Yan visited the old city many times to investigate a serial theft case, and accidentally walked into Shen Xu's flower shop. At that time, he had just finished his all-night stay and was leaning tiredly against the flower stand. Shen Xu handed him a cup of warm water and a piece of sweet-scented osmanthus cake and said, "Comrade police, please take a rest." Over time, the two gradually became familiar with each other. From talking about flowers to trivial matters in life, Lin Yan would tell Shen Xu about his troubles at work, and Shen Xu would also listen to Lin Yan telling stories about his father. The ambiguity slowly grew in their daily interactions, and they even agreed to go see the sea together after Lin Yan finished working on the major case at hand. 2. It's not that there is any hardship, it's pitiful and hateful Intention: None
