First time I watch such concept. Couple go back to there teen age. It is well combination of Divorce, Love, belive, responsibilities, misunderstanding, faith, jealousy. It teach peoples way of thinking in teen age and mature age. It shows shades of life.

Negative points are pretty obvious. If they haven't responsibility of child, then what will be dramas end? Will they came together because of only their child? The characterization of their friends, Choi Ban-do parents especially mom, Ma Jin-joo father not enough bright.

But story concept, their dialogues, comedy, ost, editing, direction maturely hold the drama at their best.
