At this time, Piper , Magnolia, and Preston are confirmed romantic options. A player's lovable status is affected by a Relationship Level referenced in the Loveable Achievement. Romantic relationships are driven by Charisma checks and initiated during conversations. Most relationships demand that you build a long-term rapport with a character. For example, romancing Preston demands you follow several quest lines with him, culminating in taking the Castle before flirtation options unlock. This is a charisma-check command, so you may want to bolster your stats with Items or Chems before trying.
Fallout 4: how to romance Piper, Preston and other companions
MacCready | Fallout 4 Companion
He is a potential companion of the Sole Survivor. Born in in the Capital Wasteland  to parents he never knew,  MacCready became the head of the Little Lamplight children's colony in , when he was only ten years old. However brazen and foolhardy he might have been in his young years, MacCready was not devoid of imagination. Children are always at a disadvantage in the wasteland, so he chose a sniper rifle as his weapon of choice, teaching himself marksmanship from the ground up. According to MacCready, engaging targets at long range meant one did not take too many chances in the treacherous Capital Wasteland to stave off death for another day. In , MacCready turned sixteen and left Little Lamplight. He took to wandering the wastelands as a gun for hire.
He also likes it if you can persuade people to give you more caps for jobs. If you talk to Daisy in Goodneighbor and ask her about being a ghoul, there comes a point where she calls you out on your supposed age and asks you to tell her what the old days were like if you really were there. If you talk about how wonderful they were, Maccready dislikes it, probably because it seems to upset Daisy to remember what was lost. If you chose to say, same as ever but with less rust he likes that. If you still can, take a job from Whitechapel Charlie to clear out some warehouses with Maccready.
As part of our Fallout 4 guide, we have all the details. Note that Dogmeat is an exception to this rule; his relationship status is always at maximum, and his perks are unlocked manually in the Charisma tree. There are 12 potential companions, but — without going into spoiling territory — there are reasons why some of them are not available for romance. Higher Charisma and Luck are a help, but you have a chance regardless. Every companion and love interest has several levels of potential friendship with you, starting at neutral.
