See: Affinity
Affinity is a companion gameplay mechanic in Fallout 4. Companions can develop personal connections to the Sole Survivor and some may ask for help with quests of their own. Each companion has a distinct personality and values. Actions or dialogue that please one companion may displease another.
Raising the affinity value grants additional dialogue into their history or the possibility of romance. Reaching maximum affinity with a companion will unlock a special perk. The affinity value is a hidden statistic, meaning it is not possible to check the progress without console commands.
