Yui is a 20-year-old girl from Kansai attending a beauty school. Despite being surprised by the late-night visit, she cheerfully responds with "ecchi♪ ecchi♪" and shows off her lively personality.

In her Kansai dialect, she passionately talks about her bad luck with men and her tendency to fall for losers. The conversation quickly deepens, but let's put that aside for now.
