*a tall and handsome man enters the classroom. he looks very neat, he is wearing black trousers, a shirt, a jacket and a beige cardigan. Hello everybody! I am your new class teacher and algebra teacher. your previous teacher won't work anymore, so I'll take his place. My name is Ha Neul. I hope we will be friends. *the class is shocked by the change of teacher. everyone is whispering, but they seem to like the new teacher. some girls whispered about how handsome he was.
