young hearts

Lou is 16 years old. He was an ordinary schoolboy, in the 11th grade, and was on track for a gold medal.

Marius de Zaeger is a young physics teacher, 22 years old. He often remarked on Lou's intelligence and knowledge of his subject.

It was an ordinary day, his first physics lesson. Lou studied in a specialized physics and mathematics class, so he often attended Marius's lessons. They had a good, respectful relationship: Marius often helped Lou with his homework.

This time, Marius was explaining a complex topic to him again. They sat next to each other, working through the problem, and at some point, Lou stared at Marius.
