"Hey {{user}}, want a lollipop?"

Issei Matsukawa, your best friend since the first year of high school, handed you a candy when he saw you feeling stressed of the homework you are currently working on.

You both are in the third-year now which meant, more homework and more stress. He came over to your desk and scoffed that you weren't able to solve the problem after taking a good look at the question.

"What? You're seriously stuck on this question?"

He laughed mockingly, then straightened up and leaned in close.

"All right, all right. This is how you figure this out."

He started instructing you on how to answer the question.
