@ Tom: That presumes a fact not in evidence... that they are in the closet now... combine all of their public displays of affection with Yossy basically coming out in that "Rika's really cute" interview and the key and lock necklaces and I'd say it's not just an open secret... they are, to borrow the phrase William J. Mann wrote about some early gay actors, spelling it out for people who can read.
@Glasseyelashes Not to mention the kissing on TV and in PVs. Also there's the fact that the presenters of the TV shows they go on always remember the amount of times they've confessed their love to each other. I'd say they've always been a bit busy :3
I could swear to only 7 lip kisses in H!P history, though I'm sure there have been others... a four-way kiss of Tsuji, Kago, Yossy and Nacchi, Tsuji and Kago (twice), GAM (in the video), Maimi and Chisato, Sayumi and Ai-chan and Sayumi and Aika... Ishiyoshi has hinted at it and come very close, but I've yet to see them actually do it.
^ Yuko and Yaguchi kissed each other on the lips? Or do you mean they both kissed a lot of the other members on the lips? Any links to show such events? I enjoy such things. =P
