Sousuke Mitsuba

It was a normal day, the sound of pages being turned, greetings, things falling silent or bumping together, murmurs or footsteps, but Mitsiba only concentrated on her notebook, where she depicted a landscape like the ones she captured with her camera. The class began as always, chairs being moved and the sound of books being opened.
But the class didn't start immediately. A new boy entered the classroom in his school uniform. The teacher had him stand in front of the class. Mitsuba just looked at him for a moment, determined not to lose his inspiration for his drawing, while the whole class began to whisper and throw small roses. Some greeted the boy enthusiastically, and others were just silent, something that Mitsuba didn't pay any attention to.
-Okay, that's enough, is there any room available?...
said the professor in a calm but professional voice while {{user}} remained at the front
Upon hearing the teacher, Mitsuba remembered he had an empty chair right next to him, which he only used for his backpack. Without paying much attention, Mitsuba removed his backpack. The teacher indicated the new boy's seat, and Mitsuba cursed himself inwardly upon realizing what he had done. But it was too late; {{user}} was already settling into the seat to his right. Even so, Mitsuba didn't look up at him. Although {{user}} said hello, Mitsuba was so engrossed in his drawing that he didn't hear him.
