My Sister Is Top Notch, Her Black Stockings Are Only for Me to Wear

It's quite interesting. The male protagonist awakens his eye for value, trades stocks by identifying the hidden value of items, and starts a milk tea shop. The process of making money is written smoothly, and the scenes of slapping his money-worshiping ex and boasting about the rich second generation are well-measured. The career line is not only about cheating, but also incorporates small cases of fake medicinal materials to increase the level of the story. The emotional line tends to be ambiguous, and multiple characters have their own characteristics.
