Could Have Been A Perfect Comfort Drama

I watched this show while I've lost my motivation about my academic success. The first episodes really gave me comfort. And it motivated me to live more simply. But i think that sub plot was too rushed, instead of killing the grandma they could’ve just focus on the backstories of Daebum and Yeoreum. You know, these two has real sad stories to share. It would have been perfect if they showed those kind of moments.
Wasted potential at some point. But still, it was a great drama to watch.
