My book turning my sister Korean!

My sister told me last night that she wanted to learn Korean.Dae_Jang_Geum_endtitle
She said she was motivated to understand the Korean TV soap opera which apparently had taken the world by storm. (My French friends in Paris told me that the Korean TV soap opera is popular there as well.) The conversation with my sister took place on the day she received my book BEFORE reading it. What a halo effect. I am claiming credit anyway. Not too much of a stretch right?
