First of all, I did check some other reviews and I was not.. satisfied. So I'm here to give my somewhat unpopular thoughts. Please read until the end. I have two major points:

1. Some of y'all 'bout to be real mad at me but it must be said... HAN JI-PYEONG WASN'T THAT AMAZING, GUYS.
Don't cancel me, listen out. I'm not saying he was bad or anything, to me, he was just average. I never wanted him to end up with Dal-mi because there was no chemistry between them. I'm sorry, but letters written by teenagers aren't any proof of love. Leaving that aside, I never liked his attitude. This is just a personal preference, though. He developed in that aspect a little by the final episodes, but just a little. I don't feel anything for characters that treat everyone super poorly and then complain that no one actually cares deeply for them. Yes, he was being a good boss, I know. Still, no one has an obligation to ''love'' him when he doesn't show any emotion.
PS: This trope in dramas of waiting for your first love for years blah blah isn't doing it anymore. Ji-pyeong should have tried banging someone else instead of simping over the girl that has been in love with another guy FOR LIKE THREE YEARS. Lmao. This brings me to my next point:

2. DAL-MI DESERVED BETTER. Her character was overshadowed by this terrible ''love triangle''. It's not her fault that she doesn't like Ji-pyeong. She shouldn't be guilt-tripped into dating someone she's not interested in.
Her as an individual was ignored by most watchers just because they were angry that Ji-pyeong was not getting the girl. Dal-mi is a great character (leaving romance aside), her perseverance and ambition yet humbleness was amazing, everything she did was to help her grandmother live a better life [NoonGil] and to prevent others of going through what her father went through [Tarzan]. Even though at the beginning of the show she said that all she wanted was to be better than her sister, we know she changed her mind and actually tried to amend her relationship with the family members that basically abandoned her when she was a child. That is character development, period, no arguments against this.
I just wish people paid more attention to her character and not the relationships she pursued.

So those were my two biggest thoughts. Other things that I can say include..:

a) Do-san was cute. I loved/hated his character half of the show; but I knew him and Dal-mi would be perfect together, I'm glad to see they even got married and are now living their lives next to each other.
IT'S JUST COUPLE GOALS, Mr. and Ms. empowered CEOs.

b) Chul-san and Sa-ha are mad cute as well! Also, I love the fact that even though Sa-ha speaks English a couple times throughout the show, they didn't revolve her character around that. I've seen Stephanie Lee (the actress portraying Sa-ha) in other dramas and they always put her as the Korean-American girl that says cool quotes in English 24/7, it's just so weird lol.

c) What happened to the revenge plotline of Yong-san, tho.. maybe I didn't pay attention to this arc being resolved.

Overall, and enjoyable show that wasn't as bad as I thought it would be.
8.5/10
