I Didn't Expect My Emotions to Be so Useful

(In a parallel world that is completely unrelated to the real world we live in) Song Yang, an ordinary intern in a financial company, accidentally obtained a system that could transform his emotions into an increase in his own abilities after his opportunity to become a full-time employee was taken away by others. After that, he began to have a wonderful life of various interactions with investment banking elites who graduated from various prestigious schools, former goddesses, old classmates with high self-esteem, executives of large companies, first love girlfriends, economic investigation police, second generation of the family, Wall Street geniuses, financial giants, industrial tycoons, etc. Instead of a harem, the main story will have a single heroine ending. There will be other main female characters, and these characters will have independent world lines to describe the issue of belonging. (Due to factors such as parallel worlds, plot settings, and the author's limited experience, the description of geography, cities, and industries in the article may be slightly different from real life. Please forgive me, readers)
