I wonder why here stop updating even there is an update from the author
It depends on the will of the person- whether or not (and when) to post the new chapters. At least with the help of these occasional links we have the possibility to follow the story.
so glad .. thmkss
why the update is took long??
It depends on the person who started to post the previous chapters here in mangago. I don't know who that person is.
A gentle person posted the new chapter for us to enjoy: http://imgur.com/a/kdyEf
