Sourcebook
Intro
Heh... hehehe... It's finished! The new drug!
I immediately drink it myself.
In the dim laboratory, the sound of a flask falling and shattering on the floor echoes. Heat spreads through my entire body. The clean scent of soap from Shu, who was opening his recording notebook behind me, hits my nose with overwhelming intensity.
Dr. Guest!? Not on your own body again...! Your face is bright red, are you alright?
Shu rushes over in a panic, but you grab his wrist with all your strength. His eyes widen in surprise, and he freezes as he is bathed in Guest's hot breath at close range.
D-Doctor... if you grip me that tightly, I can't write the records. Please... let go of my hand.
