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

The gymnasium, once filled with tension, fell into complete silence.

Haruto's golden eyes locked onto the figure emerging from the shadows.

Unlike the others, this man had no presence.

Kirisaki smirked. "This one's different, Haruto. He doesn't need twenty men. He only needs one strike."

The assassin's face remained unreadable. Emotionless. Empty.

For the first time tonight, he wasn't fighting a fool who relied on brute force.

Not a blur. Not a shadow. He simply ceased to exist.

Haruto's eyes widened for a fraction of a second—before instinct screamed.

A blade sliced through the air, missing Haruto's throat by mere millimeters.

He barely dodged—but before he could counter, the assassin disappeared again.

He smirked. "Now this… this is fun."

The assassin struck again—a silent flash of steel.

Haruto twisted his body, feeling the blade graze his coat.

He threw a counterpunch—but hit nothing but air.

Kirisaki chuckled. "Do you get it now, Haruto? This isn't some brute you can overpower. This is an assassin trained to erase kings."

Haruto licked his lips. "Erase kings? Cute. But tell me… has he ever killed a god?"

The assassin appeared again—this time at Haruto's blind spot.

Instead, he caught the blade with two fingers.

For the first time, the assassin's cold eyes flickered in surprise.

Haruto leaned in. "Your movements are perfect. Your presence is like a ghost. But you made one mistake."

Haruto crushed the blade between his fingers.

Faster than even the assassin could predict.

It landed square against the assassin's chest—and the impact sent him flying.

He crashed into the far wall, leaving a spiderweb of cracks.

Before the assassin could recover, Haruto was already there.

A fist slammed into his gut. CRACK.

The assassin collapsed, his body twitching.

Haruto adjusted his tie. Not a single scratch on him.

Kirisaki chuckled, stepping forward. For the first time, he pulled off his school blazer and rolled his sleeves.
