She don't trust anyone else except her family. All she had is her family.  As for him, he never hesitated to help others. He been known as Guardian Angel.  

I wonder if you didn't help me that day, would we be together like this? Or would we be just a friend? It's not that I'm not happy now I just wonder what would happen IF that accident is not happened. 

I really don’t understand oppa. Why oppa suddenly want to meet at a cafe? Oppa usually hate to be alone at a crowded place. We always come together. What makes more weird is that oppa will be wearing a pink knit sweater. Oppa really hate pink since it’s to girlish. What is wrong with oppa today? Why is oppa not being usual him? Why? Did oppa ate a wrong medicine? Argh I’ll get migraine if I keep thinking about it.
