I will attempt to translate although please keep in mind I'm a beginner so maybe a native speaker can correct me or shed more light on the subject. I'm honestly scared and I'm frightened... like this our emotions gradually fade away... 어느순간 = abruptly(maybe? I'm not familiar with this word)... (we) can't make contact and... just like that we can't even (try to) meet (I wonder)... I'm honestly scared... a lot... I hope this was helpful.
