Female protagonist: Shen Zhao, 26 years old, deputy captain of the city's criminal police team, fighting champion, first in crime detection rate. He has a decisive and irritable personality, rough life, and severe stomach problems. He can knock down gangsters with his bare hands, but he will choke on pearls until he coughs and sheds tears.
Male protagonist: Lu Qinghe, 28 years old, dropped out of college and opened a milk tea shop. He can do fortune telling, flower arrangement, and cat raising. He has a gentle voice, always smiles, and is fearful but has a poisonous tongue. Say in a poem-reading tone, "Stay up late again and I'll poison your American style."
