The Black Beast Enters the Mother-Daughter's Nest
Kim Il-woo wasted no time, heading straight to Choi Ara's house the very next day. 'I should keep dropping by whenever there's no class at university.' It was a weekday, so Ara's mom had already left for work. Thanks to the points he'd scored in last night's standoff with Park Jun-hyun, Lee Seo-yoon had even given him the passcode to enter the house, asking him to look after her daughter.
'Her trust level is off the charts.' Kim Il-woo punched in the code she'd provided and stepped inside Ara's home. Ara must have already heard about his visit from her mom, but he made a point of slamming the front door loudly and announcing his presence anyway.
"Ara! It's me, Kim Il-woo! Your mom told me. You home?"
He knew there wouldn't be a reply, but he announced himself deliberately. After going through something so horrific, she might be terrified at the thought of a man who wasn't family in her house, so he approached with extreme caution.
'That's Ara's room, right there.' The door was firmly shut. The same door he'd passed through so often as a kid playing over here now stood as sealed as Choi Ara herself—motionless, impenetrable. Kim Il-woo stood before it, knocked gently, and called out again.
"Ara, it's Il-woo. You don't have to answer. I just wanted you to know I'm here."
He sat down in front of her door and spilled everything: how he'd heard what happened to his childhood friend, how her mom had asked him to come by for her sake, how he'd keep showing up no matter what. He laid out his plans in rambling detail. Whether she was listening or not, he figured just talking like this would close the distance between them, so he kept at it—until, at some point, a response came.
"Get out."
A sharp, cold voice like metal scraping metal. A razor-edge hostility seeped through the door, as if it might slice right through.
"Yeah, I was thinking that, but I'll stick around a bit longer. I'll say hi to your mom when she gets back. Or was I too loud?"
No more replies after that. Kim Il-woo plopped down shamelessly in front of the door, chattering on about old memories, the mundane weather today—whatever came to mind.
'Poison and antidote in one. Classic.' What would Choi Ara do if she knew her rapist was sitting right outside her door? He wondered when his future self would break the news to her.
'Did sending my wife back in time give him the cue? Or maybe after marrying her and breaking her in completely, he got bored and craved fresh thrills—sent her back, then planned to reveal he was the rapist all along. Watch her crumble in despair... then fuck her senseless?'
'Perfection.' Kim Il-woo chuckled to himself, cock twitching at the mere thought. If anyone saw his sinister, twisted grin, they'd never set foot in this house again.
And so the black beast began nesting in the two women's precious home, holding his spot until his next target, Lee Seo-yoon, finished work and returned.
"I'm ho— Il-woo?"
Lee Seo-yoon froze at the sight of unfamiliar shoes in the entryway, her guard shooting up—until she remembered her visitor.
"Welcome back."
Kim Il-woo, who'd been sitting by Ara's door, talking, resting, talking again in a loop, greeted her with feigned innocence. Seeing him faithfully keeping vigil outside her daughter's room softened the lines around Lee Seo-yoon's eyes.
'He's minding his boundaries perfectly.' She knew how fragile her daughter was right now. Her boyfriend Park Jun-hyun had forced his way in multiple times, desperate to see Ara, only to trigger her screaming fits—he'd been chased off more times than she could count. But here was Kim Il-woo, respecting the line.
'He knows the playbook. Easy as pie.' Admiration shone in Lee Seo-yoon's gaze toward him. His future wife had mentioned how his stubborn vigil outside the door, just talking away, had been a huge help. He'd simply followed the script, and now he was scoring points not just with the daughter, but the mom too.
"How's Ara?"
"No response since she told me to beat it."
It was basically telling him to fuck off, but no need to say it like that—he softened it. Lee Seo-yoon could guess the venom in her daughter's words; a wry smile tugged at her lips.
"Have you eaten dinner?"
"Not yet."
"Then stay and eat."
Kim Il-woo started to refuse, but she shook her head, pressing gently.
"Alright, then..."
"Give me a sec to change. Wait here."
With that, Lee Seo-yoon headed to her room to change. Kim Il-woo replayed her outfit in his mind. Standard office wear, but on her voluptuous figure, it hid a devastating eroticism.
'Are stockings that destructive?' He fought the urge to stare at her fleshy thighs and calves sheathed in those coffee-colored stockings. Office guys must suffer around that pheromone bomb, he thought, tamping down his base urges—until she emerged from her room.
"I need to prep dinner, so hang tight."
"Can I help...?"
"Just sit. You'd only get in the way."
Now in a house dress that fell to her knees, she'd thrown on a cardigan to cover up for her guest—reducing skin exposure. Did she not realize how the casual, lived-in vibe made it even hotter? He was dying to hike up that hem and plunge in right then.
'Not just a killer body—her aura slays too.' The ripe allure of her mature form paired with her youthful face was potent enough, but glimpsing the refined lady's private, relaxed side at home? Irresistible. Her back as she cooked in the kitchen was the picture of an ideal wife.
'She's tempting me, right?' No other explanation for pheromones that strong, clouding his reason. Kim Il-woo gritted his teeth through the wait until dinner was ready.
"It's thrown together last-minute, nothing fancy—eat up."
"Thank you. I'll dig in."
They sat facing each other and started eating. She'd insisted he stay for dinner out of gratitude for looking out for her daughter, but now the awkwardness hit her; he could see her eyes darting. Once the initial haze cleared, embarrassment flooded in.
'Yeah, it's a weird spot objectively.' For Kim Il-woo, packed with lewd intent, it was fine—but they'd rolled naked in a motel just last night.
The only sounds were the clink of utensils, amplifying the tension.
"Mmm! Your cooking's as good as ever, ma'am."
"R-really? To your taste?"
"Yeah. Living alone, home-cooked meals are rare for me—it's amazing."
Kim Il-woo broke the ice, and she jumped in, conversation flowing. Once it started, the awkward air thawed fast; they finished in a comfortable vibe.
"Hang on, let me take some dinner to Ara."
Eating in her room? Ara's condition was worse than he'd thought. Lee Seo-yoon plated a simple meal, knocked on Ara's door, and went in. Through the crack, he glimpsed a dim, stuffy darkness—poor ventilation letting out a stale whiff. He caught snippets of their quiet talk but stayed silent, eavesdropping discreetly.
'Not time to step in yet.' With future intel from his wife, Ara was already in his grasp. He could fully win over mom first, then strike.
Lee Seo-yoon emerged soon after.
"You were being extra quiet on purpose?"
She'd noticed him holding his breath.
"Yeah. Didn't want to remind Ara I'm here—might not help."
"You've gotten sharp and thoughtful since I last saw you. Impressive."
His care for her daughter lit up her face with a warm smile.
"Then let me help with dishes before I head out."
"I'll handle those. Come by often, like today."
He'd pitched dishes as an excuse to linger, but her casual refusal left no reason to stay.
'Guess I should bounce. Can't force it.' Pushing too hard would backfire, so he stood to leave.
'But if I've drawn the knife, might as well slice something.' First time alone with a friend's hot mom—quitting empty-handed felt wrong. He decided to advance just a bit.
Suddenly, Kim Il-woo pulled Lee Seo-yoon into a hug.
"Wha—...?!"
She froze in the arms of her daughter's friend, too stunned to push him away.
"Don't overdo it, ma'am."
"O-okay... yeah...!"
Her face flushed hot in an instant. Last night's fever reignited, her lower belly tingling sharply.
'I'm insane. Completely lost it. Lee Seo-yoon, you're truly mad!'
His thick male scent tickled her nose, his sturdy arms and solid chest making her heart pound wildly. Trembling, she wrapped her arms around Kim Il-woo in return.
'It's just comfort. Nothing more.' She couldn't misread this good childhood friend's intentions toward her daughter. Pushing him away now would scream impropriety. Feigning calm, she returned the embrace.
