The Keeper's Instinct
For Dr. Hwang Jeong-geon, the line between the sessions he took for his own pleasure and the hours he spent privately training Ji Hye-in had begun to blur.
Back when Hye-in's opportunities to serve the other members had been scarce, he had kept those two things strictly separate — the time he claimed for himself, and the time he summoned her to the studio apartment he maintained as a private training space. Now that boundary had grown indistinct. He was calling her to that apartment — the hideout he had set up just for this — far more often than before. Almost constantly. With no regard for time or occasion.
There was no question she possessed an extreme submissive nature. Ordinary submissive tendencies couldn't begin to explain it. When people talked about promiscuous women, they might say she had a wild streak, or that she was the unfaithful type. But Hye-in was something else entirely. She was different from those women — unmistakably so.
"You've been busy lately, haven't you?"
"Yes... a little..."
Hye-in answered Dr. Hwang's question with a faint smile.
"Doctor... I actually had something I wanted to talk to you about. Lately, with all the daytime appointments... I've been away from the office too much. I think we need to adjust the schedule."
"Is that so? Then we can just do evenings."
"Evenings won't work. After my husband gets off work, we do a video call every day from home. So for the time being... actually, going forward... evenings are going to be difficult. Leaving the house again after I've already gone home... it just makes me uneasy. Daytime is the safest, I think. Which is why... I think we need to cut back on the hours."
Dr. Hwang had no reply.
He had spent his entire life as a psychiatrist — a distinguished medical doctor in the field of psychiatry — and yet there were aspects of Hye-in's psychology that even medicine couldn't adequately explain. No matter how much he trained her, no matter how many conversations they had, there were things she would never speak of: her past, certain specific subjects. She either refused to open her mouth entirely, or she would gloss over them with vague, evasive answers.
If he could pinpoint those exact pressure points, the training would make real progress. But he couldn't find them. And so the distinction itself had grown muddy. Was he training a woman with a genuine submissive nature — or was he simply teaching a whore the skills to better service her clients?
That was why, over the past month or so, he had been watching her every move far more closely than before, every time he saw her. Honestly, the fact that she had taken Park Young-ho — a man she didn't even know, a brand-new member she'd simply been told to serve well — and received his Golden Play across her chest, something she hadn't even properly trained for yet... that still quietly astonished him.
When you trained a beast rather than a human — when you kept animals in a zoo, and you wanted to do it properly — control over excretion was the most fundamental of fundamentals. Trying to control any other behavior without first controlling excretion was, frankly, absurd. That was why zookeepers put so much effort into managing their animals' waste. If the animals simply relieved themselves wherever they pleased, the zoo would become a complete shit-field.
A simple example: when you first raise a puppy, teaching it where it is and isn't allowed to urinate is quietly one of the most important things you do. Once you have control over the puppy's urination, control over defecation follows naturally. That was why Dr. Hwang had planned to finish her training in anal sex as quickly as possible, following on from Golden Play — even though that training still wasn't properly complete. But it had been postponed a week, then another week, the timeline stretching further and further back.
That said, Hye-in hadn't been neglecting her role as the cafe's Public Sub. Whenever the organizers set a schedule, she complied. She followed along without complaint. On days when she had work at the association office, she would even stack two or three sessions before or after — a kind of enthusiasm that was hard to ignore.
Dr. Hwang sat with all of this, turning it over in his mind.
She hadn't been fully active back then, but she had still worn the title of Public Sub — until Yeom Seong-bong, a man who couldn't stand to see her that way, had all but forced her out of the cafe. And then she had spent more than a full year with that same man — two years, counting by the calendar — living just fine after leaving. That, too, was quietly a mystery.
And what came after that made even less sense by any ordinary logic. Ko Dong-seok, who had done something stupid to Hye-in's husband, gotten beaten for it, and quit the cafe entirely — that same man had approached her privately and dragged her back in. She was a type of person that defied easy understanding. A profoundly passive human being. None of that history sat easily with Dr. Hwang.
"Strip and get on the table..."
He started to say it, then stopped. Today, he thought, continuing the training through words alone wasn't going to be enough. A different approach was needed.
"No. Strip and get on the bed."
"Yes..."
Just in case, he had taken a larger dose of erectile dysfunction medication than usual today.
"Lie face down."
"Yes..."
He had her lie face down on the bed, completely naked, not a thread on her body. Then he spread a large towel beneath her hips. And then Dr. Hwang began applying oil to her anus.
"Ah... Doctor... th-that's..."
A shallow moan escaped her lips.
"Stay still."
"Doctor... wait..."
Hye-in clenched her buttocks. Dr. Hwang brought his palm down on one cheek — a light smack. Then, a little forcibly, he tried to push one oil-slicked finger into her anus.
Hye-in, who had been on her knees with her hips raised, collapsed onto her stomach on the bed. Her ass cheeks clamped tightly together.
"Get up."
Hye-in, who had flattened herself against the mattress to protect her anus, slowly pushed herself up. She sat kneeling on the bed.
For the first time, Dr. Hwang found himself doubting the theories he had spent a lifetime studying. Perhaps they only worked on people who were genuinely sick — in body or in mind. Perhaps they simply didn't apply to a unique case like Hye-in, who wasn't ill at all. No matter how he looked at it, this didn't feel right.
Regardless — from his perspective, he fully intended to settle this one way or another today. Whether it worked or not, he was going to try something entirely different from his usual training methods. Something primitive.
"Why are you so afraid of anal penetration?"
"I-I'm sorry..."
Hye-in's face had flushed slightly. She glanced at Dr. Hwang, and the moment their eyes met, she hurriedly looked away, dipping her head.
This is the moment. He was no longer a doctor. He had decided to abandon the medical perspective entirely — to approach this the way a zookeeper approaches an animal. Instinctively. There had been too many things about Hye-in's behavior that simply couldn't be explained. He had no choice but to try a completely different approach.
Even if it failed, the cost wouldn't be high. His odds, as he saw them, were fifty-fifty. Half a chance of success. Half a chance of failure.
"B-but still... anal is..."
The moment Hye-in's words trailed off, a sharp crack rang out.
Dr. Hwang's hand had struck her across the face.
