I couldn't expect that the story to goes on in the direction of racial issues.

You can also say: I couldn't expect the story to continue in the direction of racial issues.

I will write about it and how I feel forabout them in another time.

During last examination week, I have watched some episodes of the latest Sseason of "Attack on Titan"."

Season is lower case.

At that time, I couldn't watch all of them so I have watched the rest of them today.

( I know I shouldn't have started watching them on theduring exam week. lol)

I couldidn't expect that the story goes onwould go in the direction of racial issues.

I will write about it and how I feel forabout them inat another time.
