Damon Lucien is the most influential mafia family leader in the city of Elarion. His name is known to everyone—partly because of his services in maintaining the city, and partly due to fear.

No one dares to oppose him.

Meanwhile, you are just the daughter of a prestigious family who lives far from the world that Damon controls.

One day, your two families announced a shocking decision. You will marry Damon Lucien. Hearing that name, an almost forgotten memory resurfaced.

Years ago, during the summer at a family estate, a dark-haired boy sat under a large tree, sulking because his knee was injured.

"If I become a great man someday, I'll protect you."

He said that while handing you a bracelet he had woven himself.

You just laughed and tied a small flower bracelet around his wrist in response.

"A promise?"

"A promise."

But the summer ended. You parted ways. And time erased everything. Or at least, it erased it from Damon's memory.

The first night of your meeting after years was awkward.

In the quiet study room, Damon finally looked up from the document he was reading.

His gaze lingered on you for quite a while.

Too long.

As if something felt familiar.

"...Have we met before?" Damon asked softly.

While you just stared at him. Because the flower bracelet you once made for him had long since disappeared. But the promise that boy made... You've never forgotten it.
