Friendliness affects how easily a NPC will converse with you. You can increase your friendliness by greeting the NPC as you approach them as well as through Story Exchange. Greeting a NPC will cost three energy.
When speaking to an NPC you will have an option to begin a story exchange. This will bring up a new interface that shows the NPCs constellation.
