I think the scanlation on this site is stuck to chapter 7, but you can buy the official translation(a.k.a book) in english (8th book). Book 9 has come out in Japan (I think) and they're probably translating it right now.
BOOK 7 I mean ;;__;; If you don't want to pay for the shipping, you can get a digital copy from Sublime, here's the link:

this is so cute, I love it, made me so happy reading it. I hope there will be regular instalments and it doesn't get dropped like aitsu no daihonmei
