Where can I watch this series?

Hi y'all!

One series that I've been wanting to watch for a while now is Gap Dong

https://mydramalist.com/8912-gap-dong

It's on Viki but it says it's not available in my region, and It's on kissasian I'm pretty sure, but that's one site I typically try and avoid because of the ads and stuff. Is there anywhere else where the series is available to watch at? Preferably a site with no pop ups / malicious ads.
