Yes, 'The Love Hypothesis' started as a Reylo fanfic (Rey and Kylo Ren from Star Wars). It was later adapted into an original novel, but its origins were in fanfiction.
No. 'The Love Hypothesis' is a stand - alone romance novel. It has its own story line, themes, and character development that are independent from the Reylo concept. While both might fall under the general umbrella of fictional romantic pairings, they are not related in the sense that one is a fanfic of the other.
Definitely not. The Love Hypothesis has nothing to do with Reylo fanfics. It has a completely separate and distinct narrative that doesn't draw from that particular fanfic concept.
No way. 'The Love Hypothesis' is not a Reylo fanfic. It's an independent work that doesn't draw inspiration from or relate to the Reylo concept at all.
It was fairly well - known. Many fans of the source material that inspired the fanfic (in this case related to Reylo) were familiar with it. Its popularity spread through word - of - mouth within the fandom, and as more people read it, it became one of the more talked - about fanfics, which eventually led to its journey towards becoming a mainstream published work.
