Lover's Embrace is a temporary perk that grants the Sole Survivor a +15% experience boost for 8 hours, after sleeping any amount of time in an unowned bed with a companion, with whom the player character has a romantic relationship in Fallout 4. Lover's Embrace replaces the Well Rested perk. When sleeping, the Sole Survivor will obtain one or the other, but not both. If the player character already has the Lover's Embrace perk and attempts to sleep away from their companion, they still will not obtain the Well Rested perk.
