Beyond shin-koong (fluttering heart), as in life, the relationships between characters and groups of characters is given attention in this 12-episode series.

It is interesting to watch as each character forms his or her own values, and how this affects the people around him or her.

For example, watch the dynamics of long-term friendship since middle school, co-workers who work closely together, self to ideal self, parent and child, boss to workers, sibling relationships, fan and artist.
