I have a happy life, happy family, happy job, everything in my life was happy. But suddenly, there is an unexpected accident that the whole city is now covered with fear. I have seven friends, but the two of them are included in that accident. What is that accident?

I'm happy with my boyfriend but suddenly, his bestfriend make it difficult for me. And one day I need to choose between my boyfriend who is busy but loving or his bestfriend who is a serious man but caring.
