Welcome to the Let's Encrypt Community 
Since angelsturkiye.com and stories.angelsturkiye.com are both hosted on the same server at 45.80.175.87, you should be able to secure stories.angelsturkiye.com with either this cPanel wildcard certificate:

Do you really want a www.stories.angelsturkiye.com subdomain? It's very unusual to have a www secondary subdomain. It is fully possible to get a Let's Encrypt certificate for that subdomain. I just want to be sure that's what you really want.
You would need an A record for www.stories.angelsturkiye.com pointing to 45.80.175.87 for starters.
