Undefined: Chronicles of My Relationship With Harry Potter

I can’t find the word to describe it. Does such a word even exist? How do I portray such bliss? Is that what this is? Is it ‘bliss’? Is that word even effective enough? I quickly flipped through the dictionary in my hands to find the correct definition of bliss.---> Hermione has a little trouble finding the right words to describe her relationship with Harry! Total fluff stuff.
