Next to her, Somi snorts, and then hastily presses a hand to her mouth and nose. Chewing nervously on her lip, Kisa wonders—with increasing concern—what plot, exactly, is unfolding right beneath their eyes. Korain says something in reply, but with the vacuum cleaner roaring in the background, Kisa cannot make it out. Determination lowering her brows, Kisa rises slightly from her crouch and wraps her hands around the cold metal of the cart’s handle.

“We need to move closer,” she whispers to Somi.

If either Korain or Chaeyeon notice the housekeeping cart very gradually scooching closer to them, neither let on. When they’re near enough to hear the next words, both women duck back down and exchange satisfied looks.

“—gets what he deserves,” Korain is saying in a low, hard voice. “When you let the boss know that we took care of him, we get what we deserve.”

Well. Kisa’s hands are suddenly very sweaty around the cart’s handle. This is, she thinks, exceptionally incriminating. Her anxiety mounts, and she does her best to package it up nice and neatly in a little box and shove it into a corner of her mind. This requires focus, after all. Unless the context in which she’s taking this conversation is terribly wrong, it seems that Somi and Kisa have managed to find the murderers.

Yet, even as Somi nudges her giddily, Kisa forces her mind to slow down. It’s not helpful to lose all rationality at the sight of a clue or two: even as damning a sight as this one. She still must think this through.

Eyeing the two, she writes down a list in her mind. Motives: Both were upset by Hwanin—or someone related to Hwanin—at the greenhouse party. Evidence: Chaeyeon vocally expressed her anger at Hwanin and Seokga:

“The CEO will hear about this. I’m so tired of working down here. But all my points for good behavior will be docked because of tonight. Yeomra will see my name on the list of greenhouse workers.”

She left at the same time as Hwanin. She is currently standing outside of Hwanin’s door, holding his underpants. In their conversation, they have mentioned a “boss”—somebody sent them to dispose of Hwanin?—who could possibly be Hwanung if her theory is at all correct.

Something still doesn’t seem right.

“Did you hear that?” Somi whispers so quietly that Kisa can barely hear her. “Got ‘what he deserved,’ they ‘took care of him’…”
