I agree with you, from what I'm watching, maybe it's just me taking notice of Baby Jing, but I realized about 60% of screentime goes to her. Maybe it's because she sticks with Boom, but Boom always calls out 'Jiyoung-ah' do this do that, from what I see, It's as if Boom only has Jiyoung in his world. Not only that, he praises Jiyoung frequently too. O.o but Jiyoung pwned the show. She appeared the most, beating SNSD. I have no grudge against SNSD, I'm just saying as a reason for SONEs to be angry. Of course, fans will be angry when the other party gets more attention & screen time.
In EP 3, Jing said she was worried she doesn't hae enough screentime & is worried to live up to Hara's name in this show. I think she's doing a great job so far, and is totally leading the show as a Powerful Maknae~ Even though the chief orders her around, i guess it just shows how Sunny & Hyoyeon truly are. If it was me, even if the chief favored me & gave me lesser things to do, I wouldnt even do it, I would want to hve a fair share.
Anyways, FIGHTING BABY JING , GIANT MAKNAE JJANG!
