Anywhere I can buy and read this in english online?

Tappytoon is the one publishing it. It's available on their site.

At Tappytoon it is only at ch 17.
I want more advanced chapters :)

Since it's an official Tappytoon published work, there isn't going to be another site that is licensed to sell the English translated chapters. You can only hope that a scanlating group picks up the Korean raws and releases ahead of the Tappytoon schedule.

Thanks for replying =)
