in kmh1 there wasn't exactly any evil characters instead there were ones with just grey shades
arjun's dad did create misunderstanding between arjuhi but there were times that the audience still felt sorry for him ...even natasha wasn't really evil, she actaully never created any misunderstanding between arjun and arohi and during the engagement when arjun put the ring on arohi by accident she said that she wouldn't marry arjun because he was in love with someone else...the only person tht i can think of being negative in kmh1 was paddy auntie, but she was more there for comic relief so i didn't mind her much
up till now in kmh2 i didn't really think of any of the characters being negative until todays epi with gauri....im trying to be hopeful nd think that maybe she told arohi the truth but i doubt it
i really hope the cvs change their minds abt gauri being negative...i dont want a vamp in the serial especially not the main characters best friend....i want shefali back
