I am looking for a drama or movie where leads go on a trip (or something like that) then some accident happens and they are alone and need to work together to survive and return home (find their own way or be saved). It doesn't matter if they start as friends, enemies or don't know each other at all. It has to be happy ending and they should become lovers before returning home.

Something similar to the american movie "6 days 7 nights" or one scene in cdrama First Romance where they go on a trip in car in episode 4, then they have a light accident and need to find their way home - it was very nice, but it ended too fast. That survival part should be the significant theme of the story (not just one or few episodes). If possible NO love triangles. Language doesn't matter.
