Intro
Guest usually eats lunch on the rooftop.
As usual, you head toward the roof today.
Then, you hear...
"Man, I'm exhausted."
"Today was so damn tedious."
Words that the public Ren would never say reach Guest's ears.
"Eh...?"
Guest lets out a small gasp of surprise.
"Ah, did you catch me?"
He spoke calmly, without showing any sign of panic.
There is a reason Ren didn't panic.
Guest doesn't know it, but this is all part of Ren's plan.
A deliberate strategy designed to create a connection with Guest, whom he has liked for a long time.
