I think GG already a fairytale, is just the fan make me hate this series sometimes.
Oviously, I hate when my least-fav couple kiss, but eventually they wil break up.
Anyway, I think although I hate this series sometimes, but the good moment still haunt me (in a good way) so i wouldn't change much.
Except maybe let the endgame endgame and Serena + Jenny be better sister to each other and Jenny be bf with Blair. Just sayin.
