Chapter 0: Prologue

I coveted the gaze fixed on the screen. I wished that even the attention stolen by the movie would be directed at me.

Siheon’s eyes shone with a desire that couldn’t be hidden even in the darkness.

He reached out and picked up a tangerine.

The kind of tangerine Go Kang-eun liked.
It was a sweet piece of bait to turn her gaze to him.

“You’re only watching the movie.”

“…Huh?”

He was satisfied seeing his reflection in her innocent eyes as he drew closer.

When he brought the tangerine near her plump lips, she smiled brightly and opened her mouth.

Her head tilted to meet his steady gaze, a lovely sight to behold.

“I’m disappointed.”

“…”

“Right now, I can’t even focus on the movie.”

Thinking it was the tangerine again, her lips followed his thumb.

“Ah…”

Realizing it wasn’t the tangerine, she let out a heavy breath.

Her parting lips were plump.

‘I want to suck them.’

He gazed at her wide, startled eyes and slowly moved his finger.
Gently caressing, tracing as if to tickle, then pressing down to smudge them.

Watching the soft lips he had coveted for so long distort under his finger and then return to their shape was a truly gratifying sight.

“You have a secret sweet tooth, Go Kangeun.”

Startled by his rude touch, her wide eyes wavered, clearly unsure of what to do.
He took in the sight with satisfaction before slowly lowering his gaze.

Past the tip of her adorably small nose and her warm, flushed cheeks, down to her red lips.
As his eyes licked over her, he could feel her own lost gaze wandering across his face.

He wondered if their eyes would meet again, but he couldn’t tear his gaze from her lips.
The lips he would soon devour.
Go Kangeun’s lips.

“They look sweet.”

“…”

As if heralding a deep kiss, he gripped Kangeun’s cheek and the nape of her neck.
As if the heat seething within him had been transmitted, Kang-eun began to chew on her trembling lips.

‘No. I’m the one who gets to bite them.’

He stopped the bad habit by pushing the tip of his finger between her lips.
The hot, moist membrane that wrapped around it was so ecstatic that a sigh escaped him.
Meeting her eyes, which looked as if they might cry at any moment, with his desire-filled gaze, he found her looking back at him docilely.

“Right?”

“…”

“They will be. Definitely.”

Whispering softly, he raised his other hand to cover her eyes.
The feeling of her long lashes fluttering against his palm as she blinked made his teeth itch with anticipation.

‘Go Kangeun, eyes covered, biting my lips.’
A goddamn sadistic urge surged without end.

“Ah…”

As if drawn in, he moved closer and pressed their lips together.
He stuck out his tongue, licking her slowly and carefully as if tasting her, and her breathless lips parted further.

A searingly hot, sweet breath spilled from the open gap.
The taste was so dizzying it made the back of his neck tighten.
Unable to hold back, he greedily took her lips, parting them to invade inside, but at that moment—

“Siheon, Siheon-ah…”

Kang-eun called his name and urgently raised her hand.
What she managed to grab with newfound courage was his wrist, the one covering her eyes.
Unable to even grip it tightly, she bit her lower lip again.

“Siheon-ah…”

“…Yes.”

“We… we can’t do this.”

“…”

“We shouldn’t…”

“Why not.”

His voice, suppressing the urge to pounce on her at once, was low and deep.

“Why. Not.”

“…We are, Siheon-ah.”

“Because Go Kangeun is my older sister?”

“…”

“Because I’m Go Kangeun’s younger brother?”

He lowered the hand that had been covering her eyes.
He grabbed her trembling, delicate shoulders and met her gaze.

“What kind of little brother in this world gets his cock hard looking at his older sister?”

“…What?”

She seemed quite flustered by his raw, unfiltered words.
He gave a feigned smile of composure and guided her delicate hand, which was still gripping his wrist.

Anticipation began to rise up his spine.
‘Tonight, how much will you cry?’

“A bastard like that should be caught and thrown in jail.”

“…”

He placed Kangeun’s hand over his rapidly beating heart.
He stuck out his tongue to lick his lips and, still holding her hand, began to move it slowly.

As he swept her hand across his broad chest and then pressed down, Kang-eun’s lips parted a little more.
When he let out a breath trembling with excitement, a shallow sigh also escaped from between her lips.

He relished the ticklish sensation of her small hand on his thin cotton t-shirt.
His jaw clenched, barely holding back the urge to just go wild.

“Right?”

“…”

Before long, her hand had moved from his chest down to his stomach.
He could feel his clearly defined abs flinch and twitch as if welcoming her touch.

“Siheon-ah…”

“You knew. Go Kangeun, you knew all along.”

He persistently dug into her trembling eyes, pulling out the old memories she must have buried.

Go Kangeun had known.

She knew what dreams the middle schooler Yoon Siheon tossed and turned with at night, and whose name the high school
