Two complete strangers stuck on a deserted island could learn to love one another (and yes, stay with one another after being rescued).

Agree because if you get to know that person well why shouldn’t you make a big step and love her? Its better for you because you can have a relationship with someone you’re stuck with and you know you’ll be there with him until someone comes and rescues you. But you should spend some time talking to that person, like for about 6-7 weeks and then start making plans.
