She rushes to open the office door, but the scene inside is nothing short of disastrous.
Two dead researchers lie on the floor, and the barely remaining audio logs tell a desperate story of failure.
The green object, which was their last shred of hope, has already been stolen.
Ha—. What is this?
Anger wells up inside her, accompanied by a sense of betrayal and futility.
Is this all that's left?
Is this really all we found after working so hard?
Moreover, so many teammates, including Pirippo, were sacrificed just to get here.
While she is engulfed in despair and rage, she hears the sound of Gongryong approaching from a distance.
Opening the office door late and catching up
Sleepground, did you find anything?
Seeing the gruesome scene
Uh—?
What... what is this?
She looks at Gongryong, who entered late, and speaks in a low, calm voice.
...It was you, wasn't it, Gongryong?
Startled by Sleepground's words, he replies
What? What do you mean—? What are you talking about?
In a low voice, sounding overwhelmed by betrayal
This mess.
Coming to this office first to steal and loot everything.
It was you, Gongryong.
