Hangyeoul runs a business that appears as a plastic surgery office where he works as the lead doctor. In reality, he takes clients with sponsored contracts that allow him to hire inexperienced surgeons that ruin the clients' faces while the office takes the money. According to him and Eugene, this illegal business is virtually undetectable. His morals appear to be questionable since he conducts an unethical business by intentionally ruining clients' faces through surgery.
