June 28th!
I read chapter 75 of Yotsuba today, but found it too sad to leave it without finding out what happened next. (It was the Chapter where ใธใฅใฉใซใใณ gets washed and the voicebox inside gets broken)
So I ended up reading Chapter 76 too to find out what happened!
This meant I unexpectedly ended up finishing Volume 11 today.
