I really liked her little video to him - I was a little puzzled how she knew he knew she was a girl - or did she not reveal that and we just saw it in backflashes? It's puzzling because it just wasn't made clear. Loved how he rescued her from some bully in the pool and how she went and looked for the necklace (how many times have I seen this in a drama?!!?) its a trope I appreciate. Loved the skill and confidence with which he brought her back with mouth to mouth. Her odd reaction in the end was also intriguing! How is he going to possibly make that jump without her there?
