However,... more>> her words are ignored due to her lineage as a despised rebel. The protagonist, Ricardo, who was reincarnated from a college student in the economics department to a merchant's child, struggles against the interference of powerful merchants in a class-based society. He quickly earns the animosity of his peers at the academy where he sought information. It was Alfina who protected Ricardo.
