Ikemen Sugidesu Shiki-senpai, the series this is a continuation of, may be found on MangaDex.
And adorable as all get-out it is.
It would be nice if it was uploaded here too.
... Then again when I see Hina explain that she fell for Shiki because "SHE'S JUST LIKE A HANDSOME MAN WITH BOOBS!" I can easily picture it as the opening of a gargantuan-sized can of worms. The forum's yuri moral police doesn't take kindly to such equivocal remarks.
