Both manhwa are about people in trouble (either because of fire or getting injured in the mountains), and their rescuers trying to save them before it's too late.
*Both of these are pretty realistic (the people finding themselves in deep misery, at least)
*The two of them have a strong and emotional build-up of stress and anticipation for the outcome.
<> Peak is a lot more violent and graphic than 1 Second.
