Eli, London's most arrogant genius detective, is only interested in two things in his life: solving the mysteries left by the criminal Saint-Saëns, and beating his roommate Julian to the point of jumping.
Other things, including likes, are distractions.
Until, Julian's niece Quinn moves into his apartment.
This girl can cook, draw, say London is beautiful in the rain, and wake him up with a sentence when he is analyzing the case.
For the first time, Eli discovers that life can be ignited by other things besides murders and mysteries.
He used criminal psychology to test her Christmas arrangements, trying to convince her that it would be safer to go back to London and live with him than to be alone in Cambridge.
He said proudly: "If any accident occurs, I will protect the scene, which will be very helpful in catching the murderer."
She suppressed her anger: "If I were lying in a London apartment, you could call the police faster than the Cambridge police."
"Theoretically yes, because I was the first witness."
"I'm so touched. I hope you won't come up with this weird syllogism to the people you like in the future."
But when the genius criminal Saint-Saëns wrote her into a coded letter, all attempts failed.
He discovered that liking someone turned out to be more confusing than solving a crime.
She praised him for being cute, but he said expressionlessly, "I don't have this attribute."
Then, the cute detective took the initiative to propose the next contact.
"We can build a long-term, stable, mutually enjoyable intimate relationship, but this requires a large enough sample."
The arrogant genius detective who is incomprehensible to the charm vs. The oriental beauty who looks gentle and harmless but whose identity is a mystery
