One of the must-watch. I enjoyed watching every bit of this show. The show would be a perfect choice for the office romance genre lovers. The show has a beautiful story and is well-directed. The cast members were cute and did justice to their respective characters, and the crew did a phenomenal job. The pacing and visual fx were fantastic. Adding other drama with similar scenarios and the Shin family and Kang Dang Go, like the drama, makes it even more enjoyable. I wish they would make a second season with the same cast.

Ahn Hyo Seop, Kim Se Jeong, Kim Min Gue, Seol In Ah and Lee Deok Hwa were perfect choices as Kang Tae Moo, Shin Ha Ri, Cha Sung Hoon, Jin Young Seo and Kang Da Goo, and I can't imagine anyone else playing their roles. The fact that Ha Ri and Young Seo's plan failed and took a U-turn, and both might end up with Tae Moo and Sung Hoon is crazy. The theme park and hiking scenes were a great addition to this series. I felt the ending was a bit rushed.

Kang Tae Mo-Shin Ha Ri/Shin Geum Hui
Though the relationship and name started was fake, the feeling was genuine. The interaction and chemistry between Ha Ri/Gerum Hui and Tae Moo are on-point and funny. Kim Se Jeong did a great job as Ha Ri, and the lengths she went to preserve her identity from Kang Tae Moo is hilarious. With each episode, Tae Moo and Ha Ri became closer and closer. Kang Tae Moo fell harder for Ha Ri than I expected him to. He was in full-on revenge mode after knowing Geum Hui was actually Ha Ri, but once Druken Ha Ri confessed the truth, he had a change of heart.
The fact that Shin Ha Ri was in dielema and finally came to her mind made this show more realistic. Tae Moo and Ha Ri were adorable throughout the show. Ha Ri was on fire the way she handled Min Woo and won the MVP title in dodgeball to go on a date with Tae Moo showing how she loves him. Ha Ri and Tae Moo were lovely together. The rain scene shows how much Ha Ri and Tae Moo's relationship has progressed. The final proposal scene was great.

Young Seo and Ha Ri have a unique bond. I love their friendship. They always make sure of each other's safety and care about each other.

Sung Hoon and Young Seo
The interaction between Sung Hoon and Young Seo was cute. Though Tae Moo was the first to think about proposing marriage to Ha Ri, Sung Hoon did before. Sung Hoon and Young Seo are always ahead of Tae Moo and Ha Ri.

Kang Da Go
I love his character. Though he liked Ha Ri as Geum Hui, he had doubts post-truth revelation. He wanted Ha Ri out of Tae Moo, thinking she was after his wealth. Eventually, Kang Da Go saw how much Ha Ri and Tae Moo care about each other and how stubborn they are. He loves soap operas like Shin's family members.

Kang Da Go, Sung Hoon and Tae Moo.
I love their bond. Da Go always wanted them to be happy with their loved ones. Sung Hoon and Tae Moo can't hide anything from each other and always have each other's back.

Shin Family
Han Mi Mo, Shin Joong Hae and Shin Ha Min are hilarious and lovely. Ha Ri and Ha Min are like their mother when they are angry. Shin Joong Hae is a very calm and loving father.

I didn't expect Yeo Eui Ju and Kye Bin to be in a relationship. Kim Hye Ji was hilarious, and her timing was perfect. Yeo Eui Ju, Kim Hye Ji and Kye Bin were great and supportive throughout Ha Ri.

Lee Min Woo needed to understand he lost his chance and let Ha Ri go and be content with his so-called girlfriend. Yoo Ra is jealous of Ha Ri. Yoo Ra tried to sabotage Ha Ri's life due to spite of her jealousy which caused massive havoc in Ha Ri's work life. At least they realised their mistakes.

Chairman Jin ended up ruining everything with Young Seo. He couldn't even understand and know about his daughter. But Young Seo got a family through Ha Ri, and the Shin family loves her as their own daughter.

The OSTs were excellent, and I loved listening to them.

Everyone got their happy ending.
