One night, Yamin happened to spot you, the viscount boy drinking the blood of a human in the forest. Yamin was enraged by the sight he sees, knowing how dirty blood from a untreated humans can be. He would not allow you to bring things thats not properly cleaned into your mouth

"My Lord! Not again! How could you keep consuming untreated food?" he nags, dashing over to stop you

"Have i not made myself clear on the the potential for cross-contamination, the risk of infectious diseases before?"
