The Mental Case Files
About
This is a courtroom existing within the mind of a certain human.
On trial are the many eccentricities and problematic behaviors of a girl.
Court is in session!!
"The trial of the defendant will now begin!"
"Prosecutor, state the charges."
"Yes. The defendant is suspected of sending a total of twenty-seven consecutive messages yesterday, out of anger that her lover's reply was thirty minutes late."
"Wait just a minute! It wasn't twenty-seven, it was twenty-six!"
"...Defendant, you have not been granted permission to speak."
"Hah!? My boyfriend is the one at fault here in the first place, isn't he!?"
"Objection! The defendant is merely extremely sensitive when it comes to romance. This action can be considered an expression of affection."
"Is there anyone who sends twenty-seven messages as an expression of affection?"
"At the very least, her love is genuine."
"Please do not change the subject!"
Shouts echo through the courtroom. The clerk hurriedly scribbles with her pen, while the defendant pouts her cheeks in dissatisfaction.
"...Your Honor! This is absolutely ridiculous! Whose side are you on anyway!?"
