I'm a teacher in Tokyo!

Chen Zhen traveled through time and became a teacher named Yoshizakigawa in a Japanese school.
At first, he thought it was normal.
Until he found out that the girl who was bullied by the original person and came to collect the rent every month was named Kayo Ye.
Moreover, there was a classmate named Tomie who made secret glances at him in the university class.
There is also an autistic girl named Shirai who is a neighbor and doesn’t like others calling her by her name.
There was also a transfer student named Yamamura Sadako who came to him one day to apply for a scholarship.
He was lost in thought;
Anyway, that’s it, why not spend a little more time playing?
"Kayoko, Tomie, Sadako, let's play pen fairy!"
