Simple enough, just a general guide.
Note: Relationship statuses determine how an NPC will react or act when around you and to the things you say or do. Keeping you relationship high will bring you more benefits and rewards, while having a low relationship can be potentially dangerous.
Relationship levels from Worst to Best:
Hate/Spite/Disdain/Neutral/Good/Excellent/Familial (Romantic status is only if you enter a romantic relationship with the NPC and you will receive even greater bonuses than Familial.)
Contacts/Location/Notes/Relationship
That's the format. Example below of course.
Young Joy/Luna Mountain Town/-/Disdain
Arietta/Dusk City/Looking into ultraball stolen shipments/Good
Donte/Crescent Town/Says he will have items available sometimes/Romantic
