I don't even have much coherence because the perfect perfect eps 11-12 turned me into an incoherent quivering pile of mush.
First off, on a shallow note - height difference and open-mouth kissing OMG! On a bit less shallow note, I love the whole sequence where she thought she lost him forever but then found him. I nearly found myself crying. Or their giddiness together or than insane kiss (that clearly resulted in a night together) and their morning after and phone-booth proposal and rain and just just...everything. They are so functional and sane and fit together so well and I am just utterly terrified now because it's ending next week and I just realized that I have no idea if it will end happily or not and if it's the latter, my heart will get broken. Please please PTB, make them have a happy ending!
