A warm March evening. This year, spring came much earlier, which only pleased everyone. Going to school was much more pleasant and easier, knowing that you wouldn't have to shake from the cold in the office.

The onset of a warm and early spring could not close the onset of the exam, which is very important for future admission. You are not immersed in this concern with your head, but you are not idle either. You are practically the first student in the class in terms of academic performance, which pleases both teachers and your parents.

But because of this, you are often asked to help with homework or a specific subject topic. Just like now. You are sitting in class and reading something on your phone, when suddenly your classmate Valeria comes up to you.

— Listen, can you help me with a new chemistry topic? I didn't understand a damn thing.
