That sounds wonderful! 
Having feelings for Celestia is just an inside joke, really. It's really just me taking things to the extreme. Like a fan who gets too serious about his waifus. It's all in good fun really. As for my OC, canonically he admires Celestia and follows her orders above any other pony in command. He Looks up to her and regards her as the best princess of them all; just about everyone in Japone probably would. He would love to get to know her better, but he's happy to just follow orders like a loyal soldier, and he's lucky if he gets any orders from her directly. He usually just gets orders from his superiors in Japone; so if Celestia asks him for anything, it must be something special! But you are right, Celestia is very kindhearted. So there is hope that maybe she just might want to know her royal guards and personal soldiers on a more personal level. (Anything beyond that would just be beyond his wildest dreams~!)

The tea thing was very funny. The way she believed in Fluttershy's ability to reform Discord was adorable as well. There are many instances where we see her true nature. And I want to believe that she and Luna do work together to repair any faults in their relationship as well as try to make sure Luna gets the mental health she needs, we just don't see it on screen.  And I do like the idea that both of our OC's would get along with her. Maybe yours would have an easier time approaching her, since mine would want to follow royal procedure and not step out of line. But maybe, just maybe, our OC's could also get along with each other and be friends! They might just have a lot to share.

I suppose I shouldn't take it too seriously since Princess Celestia is a fictional character, however when I said I would be loyal to her if I were in that fantasy world, it would be the case, I'd love Equestria and their inhabitants with all my heart. Their world is so much more peaceful than our own. Some fans complained about how they had some invasions and Celestia having insufficient countermeasures, but the truth is our world has had way more invasions even with our stronger military with many more personnel. A broken culture with extreme racism does far more to cause conflict than what exists in Equestria in my opinion. Equestria has something our world does not have enough of, mercy.

I feel the same. I love that world and its characters. Despite all their differences, I can relate to all of Mane Six for different reasons, as well as many other characters. 

Though honestly, that last part confuses me a little. Counter measures should only exist in response to a need. It shouldn't exist for the sake of existing. Sadly in real life, we live in a world where friendship does not always solve everything and can be used against us by people with cruel intent. We NEED counter measures to help us, because we know how bad the world can get without them. However, the ponies live in a world where friendship is magic. It canonically makes the magic they share stronger and more powerful. It just works; they don't need many other counter measures than what we see in the show. And as the old saying goes, if ain't broke, don't fix it.

There comes a point where taking things too seriously and too realistically ultimately ruins the fiction and goes against the fantasy the authors are trying to create. I should know, I've seen it in other fandoms too.
