Lin Xingchen, a computer genius girl, mistakenly sent an anonymous love letter to "Shen Tingbai" on the campus forum in response to family pressure. As everyone knows, this "Shen Tingbai" is the well-known and inaccessible flower of the high mountain in the school - the student god of the law school. Everyone thought she would get a bloody blow, but he responded in public: "I received the letter. Your algorithm needs to be optimized." A sweet cross-border "research" about code and law, rationality and heartbeat began.
