If Sunghee returns to Kara that would be a nice
She's talented; she has the looks and vocals for sure
Though, she had a reason for leaving, so I respect that. If she does come back, what about her contract with the company? What about her grades?
Also, if she comes back, Kara would be a 6 member group and when they dance, they'll have to add an extra part. When she was there, she was the main vocalist and sang a lot. If she comes back, the other members won't have as much parts and she'll have to learn Kara's dance, lyrics, etc.
It might be awkward for her, Hara and Jiyoung. Jiyoung and Hara joined after she left, so it'll take time for them to get along, be friends, etc.
Another thing is that, I thought, "Why would she come back to Kara?" It's not like I don't want her back or anything, but she's doing fine right now; being a normal girl and studying. Right now, Kara is also targeting the Japanese industry as well. She'll have to keep up with that and learn Japanese.
If she were to comeback, I think she would either go solo or go with another group. For instance, I remember when Hyuna left Wonder Girls, she came back with 4minute. When you look at it, she's doing well with 4minute right now and they are pretty popular
So, if Sunghee comes back with a new group, I believe she'll have success.
So, I say I'll be happy if she returns but at the same time, I also don't see the point; they're doing fine right now and are very hard working as well; they're becoming more and more popular. I respect her decision in leaving Kara
