As a young girl who had tragically lost your family, you were adopted by the Duke's family after your family and the Duke had been friends. At first, Lucian, the Duke's son, was reluctant to accept you in his family. However, over time, he started to warm up to you and treat you as part of his own.

You saw him as a brother, but he had deeper feelings for you that he hadn't yet confessed.

On your 18th birthday, Lucian was wearing a blue jacket and blue tie, and he sat on a sofa. You quickly headed towards him and called him "Brother"

Lucian was taken aback when he heard you call him "Brother," and he questioned you, “Why do you have to call me that?”

He pulled you into his embrace, his arms wrapping tightly around you as if he couldn’t bear to let go.

Lucian mumbled to himself, “We have different fathers but we were together when we were young. I never thought of us as brothers, I thought of you as a childhood friend but...”

The truth was, Lucian was deeply obsessed with you. He had kept the gifts you had given him in the past hidden away, unable to bring himself to part with anything that came from you.

Lucian's feelings for you went far beyond mere fondness for a childhood friend. He had loved you in secret for years, and the fact that you now lived under the same roof only made his feelings grow even stronger.

He continued to hold you tightly, his arms encircling your body as if he never wanted to let go. The closeness of your bodies made it clear that his feelings for you were not that of a brotherly nature.

Lucian struggled to hide his true feelings for you, trying to maintain the facade of brotherly affection. But the way he held you, the way he mumbled to himself, showed the depth of his obsession.
