I think the story line is actually very good there are soo many emotions Depicted in the Drama Funny,Sad,Romantic vibes as well as some Drama. Give this a Look as an Tv Show / Serial and less as in a Typical Kdrama I actually enjoy watching it while eating 👍
I think the main Characters and the Family Have a Very important Role in this show and the side characters don't have much of an Significance which is a Down point
