ISFJ + ENFP

This is historically a good match for romance - once differences are overcome. Though both only share the same (F)eeling preference, they are the types that are committed to pleasing their partners and making the relationship work.

Though it sounds cliche, a steady flow of honest communication really is the key to this relationship being successful. (F) types seek harmony constantly and are quite sensitive. Though there are likely major issues to be dealt with in the longer term, even tiny annoyances and irritations tend to brew and grow into resentment because the (F) preference tends to keep both from wanting to confront or hurt the other.
