New account login problem, plz help

I already bought Overwatch and usually play on my first account. Today, I logged out of that account and made a second one using a different email. I went through all the steps to create an account, and went to log in. When I log in, it says “ACCOUNT MISSING OVERWATCH LICENSE” how do I fix this?

If you are playing on PC, you must purchase a separate license for each account for Overwatch.

So I would have to buy OW again?

Yes.
