Well, she did try in the bath at her house, but then got seen in birthday suit by Kodaka who pretended to have been drunk. Well played dude, you spared yourself the problems hahah, the second, wardrobe malfunction lets call it, was also well played. He didn't see Yozora's full body even in a suit because she was embarrassed, and possibly out of fear that he would recognize something. And I guess Rika would gladly show him her own body if he only asked.
I do love the brother sister relations in this show however. Priceless. He really cares about her and takes really good care of her.
I'm only worried about Yukimura at this point. Putting aside his dressing in the club. This may very well impact his life. I mean, he was made to wear even a bra.
of topic, before I clicked [post] I had to pretty much correct everything cuz I'm half drunk XD
