I thought the scene in which Ji Hoo confesses his love to her, while reading, was truly sweet. The whole setting was beautiful, the house, the colours, and as you point out, their interactions were a lot more emotional to me than any with Gyun Pyo.
Count on her to fall asleep!!! :P
As for Lee Min Ho... ugh. I may just as well confess once and for all that he belongs to my disliked list. I appreciated his efforts in City Hunter, but that is more thanks to the character (the dark, sexy hero) than the actor, imo.
