He had tried so hard , he had done everything he could to save them , to repair all the cracks that had formed in their relationship through the years , but it still was n't enough . He thought that if they could overlook each other 's indiscretions , pardon all those not so innocent touches and smiles , that they could salvage what they had . But fight after fight , as they struggled with each other , against each other , Junsu slowly lost sight of what he was fighting for to begin with . It used to be like rainbows and daisies whenever they were together , but as time passed and as they grew , so did the distance between them .

Question: What may be what Junsu means when he says " rainbows and daisies " ?
Answer: None of the above choices .It means that the only people who are happy are those that have a connection with flowers .He is using the expression to highlight that they were both very happy and content .It means that life is mostly negative and will never be like when people were children .
