I have watched at least 80+ Korean dramas and even though I am a devout fan, there are probably less than 10 dramas that deserve a rating of 4 or higher. This drama definitely falls into the top 10 for me.
I am a fan of Park Min-Young's acting and roles. Once again she has demonstrated her talent with plausible success. The entire cast did exceptionally well and kuddo's to everyone that contributed to the writing, directing and producing, apart from the quality acting, the crew behind it deserves a double thumbs up.
The intensity of the relationships between Park Min-young, Lee Yi-keong, Lee Gi-kwang, Na In-woo, Song Ha-yoon, Park Min-young and Lee Yi-keong had me laughing and welling-up with all kinds of emotions while watching. I mean I wanted to pull off some taekwando moves of my own on Song Ha-yoon, Boa, Lee Yi-keong, Jung Kyung-soon, Kim Joong-hee and Jang Jae-ho's characters. Choi Gyu-ri's chatacter was fresh and energetic. Lee Gi-kwang, aw, a little too late for him and Ji-won, but ended up well with Hee-yeon. The chemistry between Ji-won and Ji-hyeok was mature and exceptional, and I thoroughly enjoyed this. Min-hwan & Soo-min - brilliant acting! Seamlessly switching between awkward, romantic, caring, attentive, supportive, anger, greed & just crazy was fantastic. It's scary to think that people can actually pull off all these personalities that well. Well done! Ju-ran, enjoyed the development of the character (standing up against mistreatment, same as Ji-won, we need more of this) and the relationship with Suk-joon. Manager Kim drove me nuts, but I enjoyed the acting and evolution of this character. Ja-ok, the crazy mother-in-law. Han-il, wealthy gramps-in-law that eventually accepted Ji-won and Hyun-mo, the doting father well done on your roles!
At times the relationships with parents and grandparents in the dramas distract too much from the lead couple's story, but it was done better in this one.
The second chances story was different and enjoyable. It developed well all the way to the end for each of the characters, which I find extremely rare for k-dramas. I was impressed for the very first time. The wrap up at the end was good, better than Queen of Tears, Dr Slump etc. The endings can be better though.
I also found that I was looking forward to the end when I reached episode 12. I didn't want it to end, but lost interest in all the other characters at this stage and only wanted to see the relationships between Ji-won and Ji-Hyeok as well as the relationship between Min-hwan & Soo-min wrapped up in the last few episodes. All the other characters' stories could have been closed off by episode 12 and not carried all the way through to episode 16.
I sincerely wish for this drama to be the benchmark for a good watch, e.g. the adult relationships were good, although too much hugging and hand holding becomes boring, rather skip some of it and show the characters playfully intertwined, I thoroughly enjoy the addition of kids and hope to see more appearances, not only as the lead characters' past lives or a quick scene at the end. As mentioned possibly end off some of the many character stories earlier in the series. These few suggestions so as to continue to progress to outstanding future dramas.
So overall, I quite enjoyed it and it rates at 8/10 for me.
