My student life is ・ ・ ・

Hello! I am Dug. 
I left so long time this board. Because I was busy, I had to write report for graduate and get ready for presentation.
Today, I have presentation in front of professors. This is the last event of my student life. Now, it is finished.
I ask question to myself,” Is my student life long time or short?”
Maybe both. All I know is hard days are finished and ・・・.
My life changes from study and work style to work and work style.
So, it means・・・.
My new harder days will begin!!
