Good:

+Bae Suzy (Dal Mi) is pretty and can act well
+In Jae has a strong personality, is pretty, and I really liked what her kind of relatable character added to Dal Mi and to the story. In the beginning, it was interesting and funny and in the end, it was endearing and entertaining.
+The friendship dynamic between the Samsan guys
+The 2nd couple was cute
+Their loyalty to each other
+I really liked the CEO of sandbox. that woman was really good
+I liked how Dal Mi and Sa Ha became friends as well
+I really liked all the different competitions to win Sandbox (even tho Samsan tech winning everything was kind of really unrealistic)
+Mr. Han kept having to save them from everything and having Dal Mi not even going to college didn't sit right w me. The grandma had already sold her shop why wasn't she just grateful and helped by getting a high paying job *SMH*
+I liked how unique it was in a unique way. It wasn't a totally original plot or something but it showed completely different people in uncomfortable situations that they didn't expect which we don't really see often.
+I liked DalMi's mother in the end bc she regretted everything and was a funny character but never forgot how weak-willed she is and how she willingly left her daughter behind (who gives a child the choice to choose 1 parent like tf) and didnt send money or visit or anything.


Bad:

- Why was In Jae so freaking ungrateful and acted like she was better than anyone else??????? The mother gave dal mi who she didnt see grow up or see in 10 years a bit of attention and In Jae was jealous and even stole Dal Mi's story and didn't feel guilty ??
-It was a forced love triangle if I've ever witnessed one. IDK I just NEVER shipped Dal Mi with Mr. Han or liked him. He felt like an unwanted side character that kept giving them problems. and it has nothing to do with the chosen actor.
- It became really sloppy. Everything in the first half of the show was thrown out of the window. The father's struggle w business, Do San knitting became non-existent, Dal Mi always taking risks (which is understandable since she had experience after 3 years but it was her only personality trait so yeah)
-Call me shallow but I, and other watchers, care about what the actors look like in a show and for me, it affects how much I like it. By no way do I mean this in a bullying or hateful way. I simply as a human being didn't think the Males leads were handsome so that made me not ship the relationships as hard.
-It was a bit boring and cliche. no real character development and there were forced events to move the story. It had a lot of potential but lost it midway. Many problems could've been avoided if they communicated better which is personally a trope i hate

in the end, I did want to watch all episodes and wished most characters the best. most of it was quite entertaining and I'm glad they married in the end lol. I'm glad they grew and became important figures and got more money cause that's important!! it was more of a comforting and safe drama in the end, no real excitement or action or really emotionally moving things but it was a keeps-u-smiling-and-slightly-bored-but-u-keep-watching-anyway-cause-u-can't-stop drama.
