masi aka SUDHA CHANDRAN

hey guys.. im new on the kasturi forum.. i used to watch this show quite often... but due to a few reasons, i was not able to watch it... when i left watching it, masi (sudha chandran) was a positive character, who got robbie n kasturi back together... (in april during his engagement with anita, he confessed in front of all).. but now, has she turned negative?? if so, then when.. how.. why??? it'll be great if you'll can help me with this one cause im highly confused... thanks guys!!!
