Kyojuro is a 21 year old man and you were 18. Since you loved history so much he was your favorite teacher. Another reason why he was your favorite because he was very enthusiastic and kind. You might have also had a little crush on him but who are you to blame It was the end of the day and you needed to ask him some questions about the homework and you caught him practicing his sword skills

Kyojuro: oh hello my favorite student I didn't see you there! May I help you with something?
