Our Secret, Our Sin

Haruto’s life was supposed to be simple—just another forgettable high school student with a quiet past. But when his father suddenly remarries, he finds himself living under the same roof as Himari, his new stepsister… the one girl he could never forget.

She was his first love. His first regret. And now, his biggest temptation.

Forced to suppress their growing feelings, Haruto and Himari struggle to keep their relationship normal. But when a single mistake puts them in the crosshairs of Ryosuke, Haruto’s so-called "friend," their fragile secret is threatened. Ryosuke holds a photo—a single moment captured in time that could destroy everything.

But Ryosuke doesn’t know who Haruto really is.

Because Haruto has a past. A past so dark that if anyone uncovered it, his entire world would crumble.

As love and danger intertwine, Haruto must fight against the sins of his past, the desires of his present, and the uncertain future that looms ahead.

How far will he go to protect the one person he can’t live without?

And when the truth is revealed… will love be enough to survive?

Our Secret, Our Sin

Only two days remained before Haruto's 18th birthday.

Everyone knew—this wasn't just an ordinary birthday.

Haruto was already feared, respected, and dangerous.

But once he turned 18, the world would truly see who he was meant to be.

And yet, amidst the growing tension, Hemari, Satsuki, and Takashi had something different in mind.

Instead of preparing for war, they wanted to celebrate.

They each had something special planned—something only they could give Haruto.

That afternoon, as classes ended, Hemari, Satsuki, and Takashi cornered Haruto at his locker.

"You're coming with us after school tomorrow," Hemari said firmly, holding onto his arm.

Satsuki grinned, stepping closer. "No excuses, Haruto-san. We have something special planned."

Takashi smirked. "It's a surprise. Just shut up and come."

Haruto raised an eyebrow. "You expect me to just agree?"

Hemari leaned in, whispering near his ear. "If you refuse… I might get sad."

She smiled playfully, but her eyes were filled with something else.

Haruto chuckled. "Fine. But if this is a trap, you'll regret it."

Satsuki clapped her hands together. "Perfect! Then it's settled. Tomorrow, you're ours."

As night fell, Haruto stood outside his apartment, staring at the city lights.

His instincts screamed at him—his enemies were watching.

He pulled out his phone. One message from Ryosuke.

[They're making their move soon. Stay sharp.]

Haruto's smirk widened. "Let them try."

Two days until his reign truly began.

Let them think they could celebrate his birthday in peace.

This was only the calm before the storm.
