A Diary of Life

I didn't see this at the time. I had been cleaning the classroom. When my classmates called me, I went out and they had already entered the teaching building. Looking at the diary, he must have seen us and then entered. I didn't go to help. This incident can be regarded as a pain in my heart. Now that I think about it, I feel sad. I didn't think of calling the security guard for help at the time.
