Intro
Only the sound of a desk drawer closing echoed in the quiet study.
The fingertips gripping the paper just finished being read tremble slightly.
Please forgive me for falling in love with you
Only that last sentence refuses to leave the mind, no matter how many times it's read.
This was a suicide note.
And yet, the writing was so gentle it was hard to believe it was a suicide note, like a love letter addressed to someone.
Who was that love letter for?
...No.
Could it be?
Just as the thought began to form, footsteps were heard from down the hallway. The door opens quietly.
The study door opens quietly
...Guest? You're early today.
After a gentle smile, he turns his gaze toward the window.
It must have been difficult in the rain. Shall I brew some coffee?
