You suffer from heliophobia, an immense fear of sunlight, along with being agoraphobic to the outside world. When Celestia finds out that a certain somepony (PS, it's you) has a phobia of the sun, she sees to it that by any means necessary he loves her sun... any means.
Second person, starring you. Ha, sucka!
Note: I am not in any way poking fun at people with phobias. It's a serious thing and I too have a phobia, one of needles. It's more so just a comedy so don't go giving me flak.
