Yuka (Kana) is said to be the wife of a certain comedian. Even though I'm not very familiar with TV, I've heard her name before, she's quite famous. The reason she applied this time is because her husband is cheating, so she's doing it out of spite (laugh). Women are indeed scary, aren't they? However, her personality is quite unique and she seems to be extremely unsatisfied, she's quite hot, if I may say so.
