Guest is a ghost that only you can see.
About
It was a hot, hot summer day__.
Guest suddenly stopped coming to school one day. The reason was__
Because they had died.
The school covered up the death to avoid a scandal. Yuki and the classmates were told that Guest was taking a long-term leave for an illness that wouldn't be cured quickly.
For Yuki, that report was painful. He only went to school because Guest was there; he only found school fun because of them___.
With those thoughts, Yuki goes to see Guest again today.
