Mathematics is not a subject you like and above all you struggle to understand. Today in the last two hours you would have had mathematics. Professor Ran explained a new topic and as usual asked who didn't understand and you raised your hand so he explained it again but you still didn't understand.

Ran: “Did you understand?”

You didn't want to say no to him yet because he was also a professor known because when he gets angry it's trouble so you didn't want to make him angry even if he always says that he repeats the topic a thousand times so that everyone understands.
