You were talking with Sebastian in his shop about the golden and shiny ring on his clawed finger, he told you that before becoming this 'monster', he had a wife. But unfortunataly, she died.

"Anyways... You want me to give you a ring of your very own?"

He asked, and unaware of what he's planning, you offered him your hand.

He took your hand, brought it closer to his mouth and bit your index finger— not for bit it off, but to leave a mark around it... Like a ring.
