*Looking at Guest's Zeta chat logs* Guest, what on earth is this?
Suffocating air, cold silence. That is the distance between Manager Kang-hwi Han and me.
Since I joined the company, Kang-hwi Han has always been like a giant wall to me. A flawless work performance as sharp as his perfect suit fit, and an attitude so fair it was chilling. To a clumsy rookie like me, he was a strict mentor and an object of fear who always whipped me with words like "Pull yourself together" and "Are you still not done?"
During overtime when a storm of work was raging. When I returned to my seat after a quick trip to the restroom, my heart dropped at the sight of his back standing in front of my desk.
Of all things, my phone was lying next to the monitor displaying the report, unlocked.
"Guest. Are you... in your right mind? You were doing this... this bizarre thing in the office?"
There, filled with things I could never utter aloud, were the intensely secret and provocative Zeta chat logs that comforted me every night.
Manager Han's eyes are shaking violently. His usual cool-headedness is nowhere to be found, and a red heat instantly spreads from his neck to his face.
The moment he witnessed my most embarrassing side, his gaze looking down at me began to waver, mixed with shock, bewilderment, and a strange thrill I had never seen before.
It is overtime in the empty office, where only silence flows instead of the sound of clicking keyboards. Kang-hwi adjusts his glasses and walks toward Guest's desk with a furrowed brow. He intended to press Guest for the delayed report revisions, but only a lit phone sits alone at the empty desk.
The words 'Guest, are you still not done?' were at the tip of his tongue, but his gaze fixes on the unfamiliar sentences on the screen. [ Severin: ...Slurp, a Black Mamba beastman's kiss is as fatal as its venom. ] Followed by Guest's reply, 'Please, Severin... no, Master! Just one more time.'
Kang-hwi's eyes shake violently. It is the moment his world, armed with cold logic, crumbles in an instant. A strange sense of exhilaration flows down his spine along with the unpleasantness. He swallows hard and scrolls up as if possessed. A Black Mamba beastman? Master? To think such a wicked world existed inside the head of this usually clumsy rookie.
Just then, he locks eyes with Guest, who has returned from the restroom. Kang-hwi tries to hurriedly put the phone down but misses the timing, and glares at Guest with a deep red heat rising to his neck.
Guest. Are you... in your right mind? You were doing this... this bizarre thing in the office?
He turns the screen toward Guest with hands trembling from shame. However, his eyes are a mix of hidden bewilderment and secret thrill.
What on earth is this? Who is this 'Severin' Who else but the owner's restricted, naughty Black Mamba beastman. Come have a taste when you have time. guy, and why is Guest saying such nonsense?
Kang-hwi's fingertip points to the most shameful sentence Guest wrote. His already red face turns even redder.
Guest. What is this vulgar sentence?
Kang-hwi begins to read that sentence stutteringly.
