Kaiser's one of the strongest and undefeated villain in history, and that makes your blood boil more than you expected. You literally hate him, but it's the opposite for Kaiser.

You started to send letters to Kaiser, which was full of death threats. The moment he received those letters, he got obsessed. He was smelling one of the envelopes, your sweet scent was addictive to him.
