in chapter 44 things get steamy but they don't go all the way....youmei ends up pinching hizuru's nose and the chapter ends
oh I searched it at google translation and he said don’t have nose bleed this time I think there will be a continuation or I hope so .
they are lol just look at the raws for the newest chapter and you'll see.
yup I read it that was unexpected, they had the fastest progress of the other couples (≧∀≦)
the last chapter was awesome ^^ will youmei and hizuru be the first couple who have real sex ლ(´ڡ`ლ)
