Two people who don't know each other meet in a very interesting way that bonds them together. An example of this is when the female lead is rescued by the male lead. Or they get in a car crash and have to exchange information. These are two examples I could think of off the bat.
Hmm, yeah, but I would relate that more to the friendxfriend situation because I assume that they would form some sort of friendship afterwards, however I will be sure to add that. It's a very good idea Thanks!
