"Emma…" he trailed off, any word he said next would only ruin things.
What could he say, this was a confession to be remembered for the ages.
All his worries had disappeared momentarily as he was reminded of why he lived; her.
He had realized that by that one red rose she had given him what she was trying to say all along, except without her having to speak a single word for him to know.
She was expressing everything she had been feeling or everything she felt for him.
All her gratitude, admiration, joy; it stood as a representation of her deep passion, how she truly loved him, and her desire for him. It was another way she said 'I Love You', and that she'd be there for him, no matter what happened, since the red rose was a sign of her never-ending commitment and loyalty to him.
She loved him; she accepted him; she cared for him unlike anyone else.
He hadn't ever wanted her more at that same moment.
