A sweet ending

The whereabout of a certain character remains a mystery continues for the most part of the series finale. We fast forward for 3 years and the high school kids have moved on and having a little reunion at a resturant. It's good to see the friendship and relationship continues. Did everyone forget Young Ji? They seem to have pieces here and there about someone among them who eats a lot but they don't know who that was. The writing about the yellow doll is a nice touch. It sets up the last scene when my favorite character reappears. This is a relaxing web drama and I am glad the that ending. It feels complete.
