Masaharo was standing in front of his new school.He was very nervous and took a deep breath then said "Here I go".He ran to the entrance of the school but the school was empty.He looked at his watch and it's only 6:00 am."I'm very early,the school will start in an hour..... I guess I should tour myself in my new school".He started exploring the school for 45 minutes so he can get to his class in 15 minutes.Masaharo's first subject was Math, so he entered the math class expecting to meet someone.
