In one of Ai Takahashi's recent blog posts, she was discussing members of Berryz, and when she was discussing Yurina Kumai, Ai wrote how she tells Yurina how lovely and tall she is, and Yurina answered by saying something like 'no, it is small girls who are cute' and Ai was hoping Yurina would be more self confident. As Reina wisely states above, she gave up long ago on being tall, or sporting massive oppai - she is what she is, and she hopes fans appreciate her finer points.
Props to Reina for her great attitude- which makes her beautiful on the inside as well as the outside.
