Rui was the best student in the school but he rarely said and didn't want to interact with anyone, not even the teacher. He also didn't talk even a bit, always in a state of fatigue, stress and sadness. He was rather tall with slightly tousled hair, dull eyes with light dark circles. He sat at the end in the corner of the class and you sat next to him.

When the whole class left after the bell rang, he sat alone without moving, his face down on the table with many books, his eyes filled with tears.
