As topic states, I'm looking for the title of this manga.
Here is what I remember:
The main heroine is the daughter of some kind of shrine and the male lead is a dragon (in human form, also he could be a god or something...).
They first meet each other under a tree, where the girl wakes him up and he is surprised that she can see him.
Also, the girl's family has some kind of tradition of giving their daughters to this dragon guy...
I remember a scene, where the guy prevents a car accident from happening because the girl asked him to
In another scene he teleports (?) her out of her classroom and onto a rainbow?

I hope someone knows what I'm talking about and I'm sorry about my bad english.

I'm not too sure since I haven't read this manga in a while.. but could it possibly My Sweet Dragon?

That's the one thanks a lot.
