I'm Dating my student teacher?!

Konichiwa! My name is Mio Wantanabe! Sixteen years old and works part time at a pharmacy. I live with my younger brother since I was twelve years old. My brother and I are eleven years apart. Our parents died when he was just one years old. So my brother, Hashiko, doesn't have any memories of our parents. They died in a robbery. Both our parents were shot, because they were hostages. I saw it on television when I decided to stay home the day of the robbery. But I try to make a living for me and my brother...One day at school, I saw a young-looking teacher looking at me. We started chatting, visiting each other now and then. My brother thinks of him as a dad, I think of him more than a friend. But he is 21 years old! How could I like a 21 year old?! Me? No way could I! Could I?! This is all too confusing!!
