I found this episode to be slower than the previous three. There wasn't as much happening, but I think episodes 1-3 were used to grab our attention which was done VERY well. I'm completely hooked. I liked how the story was slowed down and gave us a peek inside why Min Se Yi is the way she is. Which in turn, added to the connection between her and Yoon Sul Chan. I also enjoyed how the episode didn't just focus on the two main leads but gave a little more intrigue into the other members as well (like Kim NaNa who I am just fascinated with right now). All in all I enjoyed the stroll-like feel of the episode and hope the drama keeps a balance between upbeat/energized and slow/character-building.
