The question is akin to that of a couple stranded/trapped on an island with no forseeable hope of rescue.
It seems to me, that with no choice about the person available for interpersonal dialogue, the results could range from love through hate. Desire for mutual amicability rather than hostility would logically call for attempts at courtesy and compromise.
Nonetheless, love would remain only a possibility, I would think.
Of course, if one thinks of love as an action (verb rather than noun), then perhaps the "feeling" of love could result. Seems to me that even then, however, the ultimate "success" would depend on a mutual effort.
