Try to give all girls in the team a chance not only Serena it feels bad (Misty,May,Dawn,Lille and Chole) had to give up because a few interactions Ash had in the past
So some people asked me to add Jessie to Ash's harem but I only do this when atleast 25 people support this as we all know she was from a poor family background wanted to have a good life that was one of the reason why she joined team rocket as the Rocket trio was always known as good people not serious villains they are for comedy if I add Jessie to harem I will simply hook James with gardenia and let ash catch Mewoth as his own Pokemon just imagine Tyson's Mewoth vs Ash's trained team rocket Mewoth just a idea I got after reading some comments if you don't want that's also ok .
Pokemon: Reborn as ash , Make up for your regrets and become stronger
