Kahil Ruave, an unlucky duke who has no one by his side, charms all people of different ages with his demonic magic, and Lena is a maid who is unaffected by those charms. If the demonic charm from him was a scent, the room would've been flooded with a dizzying strong scent. However, Lena's eyes held no other emotion other than worry and fear. Kahil decided to use another route. His appearance was also seductive, and even though he suppressed his demonic charm, people still fell for him. Remembering that, Kahil smirked at Lena. This special treatment wasn't freely given to anyone, but... "S-save me, please..." Lena, who was barely holding her tears back, pleaded for her life over and over. It was at that moment when his expression that would 'make even the gods swoon' faded. "You're not normal. You’re suspicious."
