Yuuki is a former child model who decides to start anew as an idol. While she looks boyish and mature due to her height, she actually likes pink and cute outfits, and became an idol to be able to wear them. She sees her height as a flaw, and thinks it was the only reason she was a model in the first place. In a country where grown women can be 150 cm tall, being 164 cm tall with room to go isn't good in Yuuki's eyes. She genuinely wants people to stop using her because of her height, and to notice her other abilities.
