doubt in hosting two doamins

[insomniabear]

Hi, I am quite new in hosting. Currently, I have purchased a hatchling package to host a domain. Recently, i need to host my second domain name. I need the second domain name dispaly as a new domain name instead of a sub domain of the first one.

For example:
First one: myfristdomain.com
Second one: myseconddomain.com

Must not be: myseconddomain.myfirstdomain.com

I dont want the second domain name to become a sub domain. If I upgrade my current package to baby package, can that package archieve this result? Or I need to purchase another hatchling package for my second domain?

Upgrade to the baby plan, then make the second domain an "addon" domain. Internally, it will look like a subdomain - in other words, it will actually be hosted in a subdirectory under public_html on your account. But to the outside world, it will appear to be a completely separate, independent domain.
