I consider this drama a little gem in its genre. It doesn't have a tremendously eventful plot, no big, earthshaking truth to be revealed in the last episode, no memory loss, birth secrets or time jump - forgive me, I couldn't help it. It tells an ordinary story in a refreshingly modern way, without giving up on those elements we inevitably associate to k-dramas and make them into the shows we are all addicted to: a love triangle or square of some sort, love obstacles of various nature, parents who meddle but without being completely unreasonable or out of this universe evil and a corporate sub-plot. I wouldn't call this a romantic comedy. I think it's more of a life drama. There's romance, of course, and there's a mature, clever humour, but both these aspects are rationed throughout the narration in a sedate and yet very effective way. This is why I believe I do, I do isn't for you, if what you're looking for is a typical rom-com. The pace may deter some, and others could find the raised issues uninteresting or controversial. I loved it because it offers the viewer a range of different points of view on subjects which are very common in real life, and not so common in the Korean drama world; there's no judgment involved, no stance is presented as better than the other. It's up to you to decide what you would do and how you would react in a similar situation. A life drama is only successful when the characters are well outlined. And this is the true strength of I do, I do. I myself was amazed at how gradually and yet fiercely I got attached to some of the characters, mainly the two leads. They are both so well portrayed I ended up identifying without having a trait in common with either one. Acting is spot on. I consider Kim Sun A a guarantee. I may not like all the dramas she acted in, but it's never been due to her. She enters the character in such a plausible way, she does not create fictional characters but real persona. Always believable, never predictable. And let me add how wonderfully satisfying it is when you finally land on a drama with an intelligent, self-assured, successful female lead who does not passively accepts events but make them happen! The character of Tae Kang has been an amazing revelation for me. A cute thing who looks like a puppy and acts like one is all I believed he was in the beginning. I was very wrong. He's tremendously endearing and such a blend of childlike enthusiasm and caring maturity I couldn't help but being completely captured by him. My admiration goes to the actor for capturing the essence of his character and portraying it in such an adorable way. The chemistry between those two is also a work-in-progress. Their feelings grow as the characters grow. We fall in love with Tae Kang the moment Ji An does, not before. I loved this aspect the most, as I am usually very frustrated by knowing a truth which the characters will be oblivious about for three quarters of a drama. The secondary characters are normal people. They make mistakes, they gossip, they laugh, they get angry. With the exception of "madame CEO" - and her horrid taste in figurative art, allow me to add - I liked them all. Everyone has an arc and a role in this story. They are not thrown in just in order to fill empty spaces. The music isn't unforgettable, but I must confess the main theme is addicting and the instrumental pieces very well chosen. This isn't a drama I will run to re-watch as soon as it's finished airing. However, it has many delicious, thought-provoking and poignant moments I'll be more than happy to immerse in again in the future. I recommend this drama to everyone who likes a solid, modern script, unusually believable characters and a no-nonsense plot.
