This drama was a complete disappointment for me. The first 3 episodes were incredible and the story was being developed very well, however the author started to focus a lot on the love triangle and the romance of this drama and ended up forgetting to develop the initial plot, which besides being original had great potential, but unfortunately in many episodes the main focus of the story was the novel and the problems surrounding it, allocation of being in the development of the startup and the growth of the characters in that branch.

The worst thing is that the author, in addition to forgetting the initial focus of the drama, also developed the romance very poorly. I find it ridiculous the fact that she gave so much focus to the letters that Ji Pyeong wrote a Dal Mi, and it was not final to Dal Mi nor did he care about the true author of these letters and the feelings they gave them both. These letters literally helped Dal Mi to overcome a grief and also served as comfort and companionship for Ji Pyeong, that since the beginning was a very lonely person. And the situation of the letters got even worse when now, in this last episode, the author made Ji Pyeong say that he was never the `` Nam Doosan`` of the letters.

Another problem in this drama was the lack of scenes and development for In Jae, this character started the drama with an antagonistic air, but little by little, with the little screen time that she had, I created a certain affection for her and I wanted to see a lot more of this character that for me was more interesting than the protagonist. In Jae was one of the main characters, but she appeared less than the secondary characters in the story.

The passage of time in the story was very problematic, it seems that the author used the resource of jumping in time to advance the story, since the drama was almost over and the story wasn't moving, however, I was left with the impression that many things within the known story are poorly explained, such as the fact that Ji Pyeong stayed with Dal Mi for 3 years and didn’t take any action, it just doesn’t match his personality and I thought it was quite flawed, and also Dal Mi’s relationship with his mother and sister was developed during this time and we viewers couldn't see that.

Summing up:
Negative points of the story: Lack of development of many characters and the startup theme, too much focus on romance and love triangle, Ji Pyeong extremely wronged.

Positive Points: I got to know the actor Kim Seon Ho and I will definitely follow his next works. Another positive point was Ji Pyeong relationship with Dal Mi's grandmother, I cried in many scenes of the two of them and I think it was the most developed and coolest relationship in this drama.

That final scene of the four walking together was very forced.
