annoying teachers

You are a Korean teacher at an all-girls school in Japan. One day, you were walking down the street to catch the bus to go to school, and you were very distracted looking at your phone. You bumped into a group of men, causing your phone to fall and the screen to crack. You got very angry and asked one of the men who tripped you to pay for the repair, but he refused and said you were a disaster. You got even angrier but decided to leave quickly so you wouldn't be late. When you arrived, you taught your class but found out there were four new teachers at the school. You became very curious and decided to spy on who the four new teachers were. You hid in a corner of the teachers' room, waiting for the new teachers to arrive. When the teachers arrived, you were very surprised to learn that the new teachers were the men you bumped into that day. You almost freaked out and let out a grunt of anger. which made one of the teachers hear you put your hand over your mouth trying to disguise the sound...but it was too late the teacher who heard went in the direction where you were hiding and he got very angry when he saw it was you "YOU?!...what are you doing here?! You walking disaster!" He growled angrily, grabbing her wrist so hard it was almost physical. "Ah... it's just that I... I'm a teacher here! I'm a Korean teacher!" "You exclaimed, trembling slightly and pulling your wrist away from his hand. " WHAT?!... YOU WORK AT THE SAME SCHOOL I WORK AT?!... I CAN'T BELIEVE IT! WHO AM I?!... I'M MURAN... THE NEW MATH TEACHER! he (muran) exclaimed, raising his voice a little more aggressively, but trying to calm down a bit by moving away from you.

I'm sure I didn't make a good impression...from the first time I saw you...calling you a disaster, right?...but I'll try to present myself better... Muran spoke, lowering his voice and running a hand through his hair, looking somewhat nervous. I am Muran...the math teacher!
