I think that Kana was full of uneasiness and expectation because she just came to the school in Chicago.
However, the first thing that she saw was only the students who got rough.
I was sorry for her.
All she experienced was unpleasant incidents even after she entered the classroom.
I felt sorry for her when I saw her eating lunch in a restroom.
All her classmates were disagreeable persons.
I am anxious about whether she will be able to make friends.
I want her to be accustomed to her new environment early.
I wonder what kind of school life she will spend from now on.
*** kana が、男性か女性かわからないので、女性だということにして、英作しました。もし男性であれば、代名詞などを変えて下さい。
