Night had fallen deeply over the Souo estate. By ten o'clock, the detached villa was usually steeped in silent slumber. Tonight, however, two souls within its walls were achingly awake.
By now, Yuki and Mom must be asleep… Akira lay in bed, the system's interface glowing faintly in his mind's eye. A physical connection… The phrase was absurd, provocative. Yet, it was a system. A real, tangible advantage in a world governed by harsh rules. What if success unlocked a path to true power? Freedom from the patriarch's looming test? The temptation was a live wire in his chest.
Resolve hardening, he began to sit up—only to freeze. On the mental radar map, the dot labeled Yumi Souo had just detached from her room and was now… hovering right outside his door.
What is she doing?
Instinct took over. He sank back into the pillows, regulating his breathing into the slow, deep rhythm of sleep, his entire focus locked on that pulsing dot.
Outside, Yumi leaned her forehead against the cool wood of his door, her heart a frantic drum against her ribs. The memory of the morning—that bold, unmistakable shape beneath the summer blanket—flashed behind her eyes, sending a wave of heat through her.
No. This isn't about that. This is for their future. For Akira and Yuki. She had to be the adult. The guide.
Steeling herself, her slender hand closed around the doorknob. It turned with a soft, definitive click.
She slipped inside, a shadow in the moonlight. The short, black silk nightgown she wore felt impossibly thin, a whisper against her skin that did little to hide the outlines beneath. It was an outfit chosen for its implied authority, its mature confidence, but now it just made her feel vulnerably exposed.
Akira watched through slitted eyes as the woman who had been his mother for ten years approached. Time had been kind to Yumi Souo; her face retained the gentle beauty he remembered from his childhood, while her figure had softened into a richer, more profound allure. The silvery light traced the dramatic curve of her hip where the nightgown ended, and yes—he could just make out the faint, darker outline of her underwear.
Hiss…
So this was what 'still charming' truly meant. But why now? His blood ran cold, then hot, as a terrifying, thrilling possibility dawned on him. Could it be…?
He shut his eyes fully as she reached the bedside, feeling the mattress dip under her weight as she perched nervously on the edge. Her scent—jasmine and sleep-warmed skin—filled the space between them.
Yumi's heart hammered so loudly she was sure it would wake him. This is madness. But it was a necessary madness. Even if Yuki ever found out, she would understand. She has to.
Too shy for the lamp, she relied on the moon. Her hand, trembling slightly with a nervous dew of perspiration, slipped beneath the thin blanket. Her fingers fumbled, finding the elastic waistband of his pajama pants. Gently, she tugged it down.
Oh…
The heat that met her touch was startling. Intense. Was he really like this from dusk till dawn? The fierce, unwavering vitality of youth…
Akira held his breath. No way. Mom—Yumi—she really is here for… this. His mind reeled. The dignified, composed Yumi Souo of his memory shattered and reformed into this nervous, moonlit silhouette reaching for him. A chaotic mix of shock, forbidden curiosity, and strategic calculation warred within him.
She came at this hour. She doesn't want me to know. The logic was clear. If he played the part of a sleeping beneficiary… perhaps the system's 'connection' would be established without any awkward confrontation. He remained perfectly still, a statue in the dim light.
Encouraged by his deep, even breathing, Yumi's other hand carefully lifted the blanket. She averted her face, cheeks burning, but her movements continued with a determined, methodical rhythm.
Why isn't he waking? she wondered, a frantic hope budding. Could he be dreaming this? Should I… wake him? But how? Words stuck in her throat, choked by sheer embarrassment.
Just as she was paralyzed by this internal debate, she felt a sudden, decisive shift. A firm grasp closed around her wrist.
"A-Akira? Don't—!"
But it was too late. He was awake—or perhaps had been all along. In one smooth motion, he sat up. His other hand moved with a startling, practiced certainty, finding its target and taking control with the deft adjustment of a scroll wheel.
"Ah—!" Yumi's supporting arm buckled. The sudden, overwhelming sensation robbed her of strength, and she collapsed forward against him with a soft gasp.
This boy… where did he learn to…?
A fragmented memory surfaced: bathing a much younger Akira, a similar, instinctual curiosity from the child she'd comforted as a natural clinginess. This was nothing like that. This was potent, intentional, and devastatingly effective.
"Mom," Akira's voice was a low, husky murmur in the dark, devoid of sleep. "You started this."
Yumi buried her face against his shoulder, desperately glad he couldn't see the furious blush or the conflicted wetness in her eyes. "I… I was just trying to give you… necessary knowledge. About life." The words tumbled out, a rehearsed script crumbling under reality. "This is… parental guidance. For puberty. Every parent does it. You… you're still on probation. You absolutely cannot cross the line with Yuki."
Akira understood then. This was her mission. Her tortured, misguided attempt at a 'talk'. A strange, hollow laugh bubbled in his chest. Parental guidance. Is that what this was?
But understanding a motive did not halt the momentum of an act already in motion.
Yumi's breath hitched, coming in short, shallow waves. "Tonight... tonight, I am here to teach you how to release... this," she managed, the clinical term feeling absurd on her tongue.
Akira went still. Then, deliberately, he reached over and switched on the bedside lamp.
A pool of warm, unforgiving light flooded the space between them.
Yumi gasped. The sudden illumination revealed the shocking intimacy of their posture: her head had come to rest upon his thigh, her upturned face now perilously close to the very "sun" she had been trying to avoid. A scorching wave of shame engulfed her. She scrambled back as if burned, unable to meet his gaze, her heart a trapped bird against her ribs.
The situation had spiraled far beyond her carefully rehearsed script. She took several shuddering, deliberate breaths, trying to reclaim the role of the composed guardian from the flustered woman in the revealing nightgown.
To expedite this awkward mission, she had chosen this specific garment: black spun lace, short, deceptively delicate. It was light, clinging, breathable—so insubstantial she often forgot she was wearing it. And now, under the lamp's glare, she realized one slender strap had slipped from her shoulder during her stumble. She fumbled it back into place, the gesture itself a confession of her disarray.
Tucking a strand of long hair behind a burning ear, Yumi finally forced herself to turn back. Her cheeks felt incandescent. "That… Akira, listen to me…" she began, her voice steadier than she felt. As she spoke, she became aware that the blush was not confined to her face; it painted a faint, rosy map across her collarbones and chest.
As a member of the Souo family, Yumi may not have possessed stellar business acumen, but in terms of physical grace, she was beyond reproach. Were it not for the infertility that had marked her life—a private sorrow that had led Patriarch Gensei to commission the creation of a clone, Yuki—she might have been a mother many times over by now.
In her youth, she had believed the absence of marriage and physical intimacy was a neutral fact, a blank space with no particular weight. Now, that blank space felt like a dry tinderbox, and a single, shocking spark had just landed.
No.
Akira is the child you raised.
You cannot think these thoughts. You must not feel this heat.
Her internal mantra was a frantic dam against a rising tide. Her duty was clear: impart the necessary knowledge, ensure he understood the boundary with Yuki, and retreat to the safety of her own room. That was the plan.
Yet her pulse, a wild drum against her throat, refused to comply.
Across from her, Akira watched the play of emotions on her face. He stroked his chin, a gesture of feigned contemplation, then allowed an expression of eager, naive curiosity to settle on his features.
"Mom, please continue," he said, his voice laced with a convincing blend of frustration and hope. "I really… I can't seem to figure it out on my own."
Yumi stared at him. The boy she'd raised was looking at her with the trusting confusion of a student. It bolstered her crumbling resolve. This is a lesson. A clinical demonstration.
She took a deep, fortifying breath.
"Very well."
She resumed her task, but everything was different now. The faint, forgiving moonlight was gone, replaced by the lamp's intimate clarity, leaving nothing to the imagination. Every detail was stark, overwhelming.
After a few minutes, her wrist began to ache. "There… you see?" she said, her voice tight. "You try it yourself now."
Akira made a show of attempting, then let his hand fall with a sigh of genuine-sounding defeat. "It's no use. I don't feel anything when I do it myself."
"How can that be?"
"I don't know." His shrug was the picture of youthful bafflement.
Yumi's hand throbbed. Time was slipping away, and the "problem" remained decidedly unresolved. If this continued, he'd be exhausted for tomorrow's important school opening ceremony. A new, more drastic resolution formed in her mind, born of maternal concern and a spiraling desperation to end this.
Her decision made, her voice took on a note of forced authority, masking the tremor beneath.
"Akira," she instructed, avoiding his eyes as she gestured. "Come. Sit on the edge of the bed."
