Forced Love: Flirting with the Boss

She had three younger brothers, the first two were not related to her by blood, but the last shared the same mother but different fathers.
The first younger brother hated her.
The second younger brother resented her.
The third younger brother avoided her.
She smiled.
The first younger brother didn't know she had almost died for him at the freezing seashore.
The second younger brother didn't know she had allowed the whole world to misunderstand her as a great sinner for his sake.
The third younger brother didn't know that, in the last year of her life, she counted down the days for him every day.
Later, the first younger brother with teary eyes, clutched her frantically and said, "If you were to die, I would die with you."
The second younger brother knelt before her, clutching at the hem of her garment, "I beg you... please don't leave me behind again, alright?"
The third younger brother, wanting to give all his blood to her, "Sister, how about trading my life for yours?"
