They all did well, even though they did lip sync some parts. The problem with Hani is NOT that she lose her breath, or that she cannot sing. She sang so well in Pat Pat the performance right before this. She sang well in Dasoni too, she is a very good vocalist. The problem is that it seems like when it comes to their title song performances (as I have noticed), Hani intended/purposefully did not sing some of her parts, or did not put more effort in like Jung Hwa does, some are important ones too, this is what she needs to fix, since the part she sang live sounded nice and very clear, it is not because of the dance neither, the dance is easy enough for her. I am looking forward to it Hani-ah:)
