Once your reach the maximum threshold, which doesn't take long at all depending, the romance is essentially complete, much like getting married in Skyrim. Instead of just having the option to marry an NPC immediately with the necklace of Mara, you have to build affection, similar to a BGS game. In truth, the romance system in Fallout 4 is just the Skyrim system with a few tweaks. However, what I was expecting was something with a bit more substance than Skyrim. I would never expect BGS to do anything that extensive because they have no history or precedent for it.
First and foremost, I want to preface that I was not expecting BioWare/CDPR-level romance, six scenes, etc.
