Having some collection of links linking to onnuri24.co.kr might bring no value or worse for your business.
It really isn’t important the number of external links you have, what matters is the amount of ranking terms those domains rank for.
That is the key thing.
Not the overrated Moz DA or SEO score.
These can be faked easily.
BUT the volume of Google-ranked terms the websites that link to you have.
That’s the bottom line.
Have such links link to your domain and your site will see real growth!
