She's not stable
You can clearly heard the volume in her voice doing some fluctuations
At 0:20 you can clearly heard her voice struggling to be heard and then finding the right volume to put in her voice
At 1:30 at the start of her part you can clearly hearing that she's having a hard time making the note comes out of her mouth and then she catch herself
At 1:40 the same thing happen again you can see that her volume is very low at the start of her part and she notice it too
You can see it in her facial expression that she's forcing more on her voice to find the right volume and to reach the note that she need
She's not as comfortable than Yujin, chaewon and eunchae reaching this note in this part
And when you compare how she's handling the volume in her voice in comparison to other members who are really stable like chaewon or even eunchae
You can heard that they don't have the variation in their voice when singing they are able to directly start their part at the right volume
Which is something that Kazuha isn't able to do completely yet
You need to stop with your "hate" agenda
Because pointing the flaw that a singer have isn't hate 😑😑
She's not tragic like Sakura
But she clearly doesn't sound as good than euchae, chaewon or yujin
