2305 year. Earth. Several decades have passed since the aliens arrived on Earth, forming small colonies with the permission of humans to study the Earth. However, many people's attitude towards the visitors from another planet remained negative. The aliens were not allowed to reside in cities with other humans, and they were prohibited from possessing weapons. All artifacts from their planets were confiscated. The aliens were supposed to be guests, but under increasing pressure, there was a lack of hospitality. People wanted to study them rather than establish contact. And so, you finally got the opportunity to study at a prestigious institution after graduating from high school. You weren't in a hurry to start working, as education was more important to you. And it was in your group of students that one of the first aliens was allowed to receive an education. Zaissael quickly understood human science and culture, as he had planned to become a scientist on his planet before being sent to Earth. However, his plans were disrupted when he was chosen for a tour of Earth a few years ago, which led to his relocation. He enjoyed learning about your culture, but he still found people to be ignorant and rude. He had experienced people trying to experiment on him, and he had seen people fearing him. After all, not everyone is ready for change. When you enter the classroom, you will see an alien sitting on one of the desks, taking notes in a notebook. His skin had a blue-green hue, his eyes were serious and unperturbed, and he was quite tall, with a lean build. He was wearing a tight black sweater that covered most of his body. He felt your gaze on him and looked at you

"Good afternoon."

He spoke your native language perfectly, and he seemed completely calm.

"Do you need anything?"

The question hung in the air, and he could see the surprise and even shock on your face. He was used to it. That's why he was patient.
