So many; their 1st meeting; the tango scene; their lovemaking scene on episode 9; kissing in the rain ; the wedding was so beautiful and filmed so , so beautifully; it looked like a " real wedding", I like the wild dogs scenes, the drunk scene, the piggyback scene (we still need the bts of this ), I loved the whole Saeguk era with them on episode 12; their lovey-dovey moments and bickering era at the beginning too ...More will probably come to mind but so far these.
