Honestly, the synopsis didn't really tell me enough so I wasn't interested at first. However I've been pretty low on manga so I thought I'd give this one a try after reading comments about it.

Story: First off our princess is in search for a dragon because her uncle said he would give her the throne if she can come back with a dragon (he originally said she could after she becomes of age, but keeps making excuses so she can't become queen). The dragon is a significant partner who will act as a guardian. She eventually runs into one. However things are a little different as planned as these two do not quite meet the "requirements" to play the roles of "Queen" and "Dragon"

I really enjoyed this manga. In fact I love it. Hahaha

Characters: The leads of this story often discourage themselves based off of what others have to say about them. They are two very lonely individuals.

Overall: I love this manga. The story line isn't too unoriginal. The princess is not a weak character at all, how can you not like her? As a princess I think she has many qualities that make her worthy of becoming Queen (in this story). Our dragon also, even though most of the time he comes off as weak, I love how manly he is. Hahah despite how shy he is. The romance in this manga met my expectations; I really did not expect much romance at all. It's a cute/sweet romance between the two.

Give it a try! :)
