What does "love" taste like?

It has always been felt that the human sense of smell, as a relatively dull sense, is the most acute to a certain extent. Unlike other senses that acquire the most direct surface information, smell is a sense of high integration with the surrounding environment, and smell is the free and fleeting soul to be captured. Especially when you get close to a person to get the smell on his body, the unique skin smell from the other person’s body is a specific symbol, and they are transmitted to the brain through your olfactory nerve, aside from the analysis at the physiological level, this is A confirmation of the identity of the soul of the other party, depicting a person's image, personality characteristics through smell, or sketching a dream-like picture. That's why users of perfumes use it as a miraculous hallucinogen. Invisibly shaped and tangible, sultry. So some people make perfume out of love, or name perfume as love. People murder love in order to obtain love to obtain endless love, and let its smell drift in the wasteland of erotic explosions, or linger in tender and lingering dreams, attracting everyone. A person who lacks love and longs to be loved! If there really is a bottle of perfume called "love", which can make everyone fall in love with him instantly, then I will think what is the smell of "love"? This is the first time I watched a German drama, and the overall feeling is good. The interweaving of reality and the past shows that the plot highlights the characters and inner consciousness. But in the end, in order to pave the way, the plot line of the investigation is ignored. There is no detailed explanation of the murder process and experience of the murderer. It only throws out a few clues, which makes the ending a bit thin.
