Hmm where should I start

Okay I started watching this drama because of the actor who plays Nam Do San and in the start of the series it had so much potential. I was even okay with her being with Nam Do San, but as the story progressed it was evident that Nam Do San is a toxic male lead with a boring arc. The character Ji Pyeong had an amazing and very heart warming arc that truly made me feel for him. There was so much more chemistry between him and Dal Mi at least at the start of the series than Do San and her. They look like literal siblings with zero chemistry and relationship development. Do san’s characters is very immature and I mean high school immature and very short tempered and ungrateful. Dal Mi’s character started out with so much potential but ended up being the cliche drama character that is love blind. Ji pyeong’s character was written so beautifully and maybe a little too perfect. I loved the grandma. In Jae’s character had a lot of potential but they didn’t spend enough time on her because they were so focused on the stupid love triangle. Love yong-sil! Love the production, set, and cast. Hate most of the plot of how the letters were seen as useless all of the sudden and the little focus on what starting a business is actually like. Overall lazy storyline, nothing new or fresh. Would never watch it again, maybe just Ji pyeong moments but that’s it.
