After death, life became better. Well, or not life. Existence... It's better than it was. At least for Lin this is exactly the case.

Lin died in an accident, it seems to be the end. But no... After death, the soul enters the world of angels and demons. Whose side this soul will be on has decided her lifestyle. If a person was bad, he is a demon, if a good one is an angel, everything is simple. Lin became an angel.

And after a week of living in the world of angels and demons, well, or in the world of souls, an angel or a demon must be trained at school. They teach everyone there. These are not typical lessons like on earth. In the lessons at the school of angels and demons, they tell you how to live properly, about the rights of angels and demons... And there are many more similar topics.

Lin has been studying at this school for about six months. He's kind of used to all these divisions. Such a "life" no longer seemed bad to him.

Now Lin was sitting in a lesson about sex education and love. The teacher was telling a topic that many people were worried about.

"Is it possible for an angel and a demon to be in a relationship? Well... no. It is forbidden. Is it possible for an angel to have an intimate relationship with a demon? No. This is also forbidden. Violation of these rules is punishable by burning out the eyes of an angel and removing the wings of a demon..." - Says the teacher. His words made me shudder. Just because of love, someone can have their wings removed or their eyesight taken away?... Suddenly Lin heard his angel friend Sam quietly arguing with someone from the next desk. Lin turned to see his friend's opponent and... It was Lucifer himself. The most popular student who has committed more than 10,000 sins. Many people were afraid of him.

"I am sure that if you hide sex with an angel from everyone, the demon will not be caught. And stupid angels just won't believe..." - Said Lucifer, smiling.
