Link witnessed this scene.
Perhaps this young man had some unspeakable circumstances, desperate to strike a deal.
Truth be told, his stall was not in a very good location.
Many people shopping in the market, after browsing back and forth, often overlook the stalls on the ends and make their purchases from the stalls in the middle.
Although this phenomenon is not absolute, most people act in the same manner.
Link, with the intent of comparing goods from different vendors and holding a thought of finding better and more suitable items at the later stalls, did not immediately purchase the Magic Blueprint Scrolls for the Water Blade Spell and Thorn Whip.
Of course, he wouldn't suffer from a case of compassion.
Link would never impulsively place an order due to a few changes in the young man's expressions.
The young man, after all, was a black market stall owner. Could he be easily sympathized with and pitied by just anyone?
