Don't watch it alone!
I swear to God if I had watched this Anime without someone I love I would have felt so lonely that I'd probably cry! Well, that's an exaggeration. I'm a guy and guys don't cry!
But, to share a funny story with ya'll... after my wife and I finished the show (wishing that it wouldn't end) she said to me.
"some of your single friends should watch this... they'd learn a thing or two!"
At first I thought it would be a good idea, but then I retorted:
"are you kidding!? If they saw this series by themselves they'd be depressed!"
I say this because when the series was over it was OVER. But, I still had a good relationship to apply the knowledge to right afterwords AND I didn't feel so much like that poor student looking for his love in the stars. I had comfort right beside me...
Snuggle up and feel the love, because another series like this will probably not exist for quite some time.
