I cannot get my favorite theme "almost spring" for my wp.org blog

Hi, I am new to wp. I have a wp.com blog, then I plan to switch to wp.org, because I like to add some plugins. Now after 2 days struggling I got it works. The current problem is I cannot get a theme “almost spring” which I use for my wp.com blog (https://meistudiostudents.wordpress.com/). I googled and only got one called “almost spring with adsense”, I do not like it because it has adsense ads inside the post.
Is there some thing I could do to get it?
Thanks in advance!
