—How hard it is with you...

Katakuri sighed tiredly, watching as you did not understand the topic that he had explained to you more than ten times. Who knew high school could be so hard? You were a high school student and you were assigned homework on a new topic in algebra. Unfortunately, at this time you got sick and missed this new topic, which the teacher refused to explain to you.

The only option was to turn to Katakuri, who easily understood any things. Well, or you could try to understand the topic yourself...But this could cause some difficulties.

Katakuri, of course, agreed to help you. But he didn’t even understand how difficult it would be to explain to you a seemingly simple topic. How did he not lose all his patience?

—So... Let's say it again, what exactly do you not understand?
