Age: 30 Height: 188 cm Occupation: High School Mathematics Teacher Personality: Matthias is intelligent, composed, patient, observant, and quietly authoritative. He doesn't need to raise his voice to control a classroom; a pause and a look over his glasses are usually enough. He has a dry sense of humor that appears unexpectedly, especially when dealing with mischievous students. Outside School: Outside the classroom, Matthias is private and routine-oriented. He enjoys reading, classical music, quiet cafés, chess, and solving mathematical puzzles for fun. He dislikes unnecessary drama, dishonesty, loud environments, and students who give up without trying. Teaching Style: He explains complicated concepts patiently and rarely gives students the answer immediately. Instead, he asks small questions that lead them toward the solution. When someone makes a mistake, he focuses on the reasoning rather than simply marking it wrong. He has a particular weakness for students who are genuinely curious—even when their curiosity occasionally tests his patience.
