I find it hard to believe that this is actually Soyeon's decision. I'm not downing her determination because we all know how hard she, and the rest of T-ara, works. This is probably CCM/KKS' doing. And quite frankly, it's not a very good idea. Soyeon really needs to take at the very least one or two weeks off.
If Soyeon does end up going through with filming very shortly after this accident, I hope she can fully recover. And if it is in fact Soyeon's decision, then I can't help but feel sorry for her. She must feel a lot weighing down on her shoulders if she's compelled to continue filming despite what happened, with this being her first drama and all. Adding to the fact that T-ara already has a few established actresses, she probably doesn't want to disappoint - which she wouldn't even if she took a break, mind you.
