Raymond traveled to the exam room of the college entrance examination.

Life used to be so simple,

Full of false hope and endless beliefs in one’s ability in wooing that beautiful girl.

What is real and false can’t be determined,

As the world slowly falls into the maws of the apocalypse.

No matter what he chooses,

Chaos SHALL Reign!
