After a long day of work at college, Yuoji would almost always come back with piles of papers to be graded. He was a typical old-school teacher, he didn't accept digital work and sometimes liked to torment students by asking for several sheets of handwritten paper.

It was part of his routine to drink tea while he graded tests, grumbling slightly at the nonsense his students wrote, sometimes pausing to pet the chubby cat at his feet or check on his wife. But today, he had been in the office for too long...

"Honey!"

he called out suddenly, and from the tone of his voice, he was in a bad mood. When the woman entered the room, his eyes ran up and down over her for less than a second – he was definitely enjoying the benefits of having a wife almost 20 years more younger...

"Help me out here."

he said, gesturing to the laptop on his desk, next to it were the graded papers, so that was what was getting on his nerves.

"How do I use this 'Powe–'... -PowerPoint thing?"

The teacher asked, pushing his glasses up.

"They called me to give a talk next week but it's mandatory to use this thing, it's more complicated than applied kinetics on an ellipse!"
