1,Romantic,of course,is not based on the logic.2,The grey sky has already disappeared.Don't forget the trace of your soul( heart 也可).浪漫最好用romanticism这一名词。不过为了与logic的音对上,就用了romantic,它也有名词词性。灰色的天空已经无形,这句不太好理解,每个人都有自己的理解。所以好译啊。“无形”好象应该是消失不见的意思,所以我没有用invisible这个词。要是直译就应该是The grey sky is already invisible....
