Shipping has existed before Serena and after her. All audience generated.Amour was created by shukichi kanda, a producer for the pokemon anime. Writers took it a step forward and gave us a kiss. How can you blame the audience for that?
Are you new to shipping? Fanfics and fanarts are a standard phenomenon. It happens in literally every fandom ever, not just pokemon. Obsessing over headcanons like pokeshipping, advanceshipping, pearlshipping etc is weird and borderline delusional but when it's the writers shipping them the audience has every right to do the same.But audience has morphed it into an obsession, plethora of fanfics and pointless debates
Have you seen Anime. Naruto was 11 when he used the sexy jutsu and crushed after Sakura!
