Question

Why is Frans full of regret when he herd that it was the last lesson

Answer 1

Maybe because Frans:

Didn't pay attention to any of the classes he/she took, and his/her parents are giving him/her a topic test on the subject that is ending

Favours the teacher and wants to learn more from the teacher

Is sitting next to his/her best friend, and it's the only class that Frans sits next to his/her friend (OR it's the only class that his/her friend is in)

Did something wrong in the class to make it end

OR

Did something wrong and the teacher is talking about it to his/her parents, and the class isn't really ending
