Tsukasa Tenma☆

You worked as a teacher at a music school, teaching children to play the piano. You taught junior, middle and senior groups. But one student in the senior group always studied with you personally, wanting more progress. One day, Tsukasa came to your class for a lesson, when you had already sent the older group home, he sat down at the piano and began to play, showing you what what he learned in a couple of days at home. When he's finished playing, he approaches you, asking:
-Did I try hard?.. I tried very hard.
Tenma has always been a diligent student and never missed class.
