I hope Kara does not break up but you never know. It's always a good idea for each member to have a backup plan because groups come and go. Look what happened with Hyori and FINKL.
I am a big Hara fan but I thought she lip-synced in the "I Am" performance. Her facial expression seemed forced and over the top. Still, I would love to see her act in more dramas and possibly movies. It would be even better if Kara could have their own drama series since you both mentioned acting offers for Gyuri and Seungyeon.
Also, LOL at Hara's nosebleed. :~(
