Life is based on happiness, and love is based on reciprocity?

"Life is based on happiness, and love is based on reciprocity." This sentence is the mantra of "Miss Wu" in Northern Ireland. With the popularity of this TV series, this sentence seems to be implanted in some people's hearts. This is really a good wish, to be happy and get the expected benefits. However, in an impermanent world, life is often bitter, and it is true that life is short. Happiness is based on eliminating troubles and paralyzing nerves, so no one will be really happy. At least in love, you can't count on benefits. Love is a part of life. If life is unhappy, how can love be beneficial? Wu Jie, the spokesperson of this sentence, has been pursuing interests, seeking higher seats, bigger houses and more tickets. It was not until she met Wu Di, who was called "the younger brother without wolves" by her brother Wei Wu, that she gradually learned to be content and give in. Wu Wei left because she felt that being together could not be mutually beneficial. Wu Di, a younger brother with poetic temperament, never saw brother Qiang for the last time. The wolf's brother thinks that he didn't understand life in the past and doesn't want to see his brother who is "as smart as a fool". Taking reciprocity as the benchmark and happiness as the principle is a very utilitarian slogan. If you think deeply, it is not difficult to find that the writers in Northern Ireland persuaded the audience in this way. In love, it is not only the elegance and romance of Guan Yu's pigeon that burns its glory, but also a happy marriage, which inevitably leads to "the mulberry will wither and its yellow will not die". It is a wait for "where to miss the bright moon building".
