So I realized that it's not the only love circumstances. I do not believe that if you are not, the more loyal friends than lovers. Even though I am busy fall in love,and I outsider you,,you won't hate me forever,but you will scold me with some intimate words. I do not believe that if you are not,friends know listen to other better than lovers. My implication, the words what I do not mean. I cannot leave my darling,but I even couldn't leave you.
