1. How much do I love that Jin Ho and Gae In really are best friends turned lovers. Their interactions are so pitch-perfect - teasing, matter-of-fact romantic (he says he can't live without her in the most prosaic way possible :P), comfortable and even sexy (the bit where they were both going a little batty with lust in their separate rooms = adorable). You really see 2 people who fit so perfectly well you can't imagine a better match.
2. Chang Ryul and In Hee should go fry in a pit of oil. In Hee more than CR though because CR is just her stupid patsy. Speaking of people who should fry - oh, can Hyemi die already? At least In Hee is clever, Hyemi is just a shrill boring moron with supreme irritating skills. Oh, and while we are at it, Jin Ho's Mom, FU - what, Gae In is not good enough simply because she used to date CR at one point? Ugh.
3. Did anyone else think Josef Fritzl when they first heard that Sang Go Jae has a secret basement? LOL. I totally did. I always thought there was something fishy about Gae In not remembering her mother (she was plenty old enough to do so), and now ( spoiler for that part of the plot, ep 12 )
