Well, it relates because there's a little bit more to it than that. Yeah, they both got hit by love buzz pretty hard. They were also both completely aeare of the other's attraction to the point that he didn't just tell her he was attracted. Very early on he met her at a pub or something (a social setting) and laid all his cards on the table. He told her everything. Everything. He was forthcoming about his intentions without playing games or being creepy aggressive. And then he left it up to her to decide and gave her whatever space, respecting whatever boundaries she required to feel safe and want to move forward.
Cause that's kind of a lot, right? So much so soon. It only worked because they were both feeling that love buzz so obviously and so strongly almost immediately.
I tend to think that for people who don't experience genuine love buzz often, it's stronger than for those who seem more to be infatuated with the idea of love than with the actual people they are attracted to.
For the rare love buzzers, it's so strong as to be overpowering. They don't recover from a failed attempt as quickly and the whole thing is somewhat excruciating. A lot of that is because they take themselves too seriously and put too much emphasis on what are essentially pheremone reactions.
I also tend to think people who experience love buzz infrequently tend to make the best lovers.
But love buzz and love are not the same thing. Having the first one doesn't automatically translate to being able to uphold the second one or the courage to get there.
