The setting makes no sense. The MC runs a small animal clinic, which the author claims is doing poorly. The reason being that a bunch of large and unethical animal hospitals have lost business to him. Instead of turning on their actual competitors, they all decide to send people to harass an obscure clinic.Also, it's hilarious how the MC decides to keep prescribing stuff despite instantly curing anything with the system, in order to earn money. In essence, the MC began running an unethical animal hospital himself.
