HOMEWORK:

 A. If you could own your own business, what would it be?

If I could own my own business, I want to operate my Youtube channel. I am enjoying Youtube channel Eva, Roha and a poet's vlog(It's a channel of Korea poet Boyoung Moon). They usually share their daily life. And I want to! I have planned to start my channel since I graduated from university and entered graduate school. Or I will marry, Vlog content will be more abundant.
