starting with the relationship of the protagonists, who at first I have to admit that I was able to empathize with them. But as the chapters passed, it stopped being a romantic relationship and became a sentimental dependence on the part of the protagonist.

I didn't like at all how they treated Kang Ju Yeon's character, his ending, although he did learn things, it seemed very sad to me, and the relationship with his friend seemed too forced, for both of them to have a "happy ending"

Not to mention the lack of development that Baek Hye Yeon had, I felt that I never understood how she lived her life, she wanted to give the air that she lived her life freely and didn't know how to take advantage of how crude the working life of a young woman in a world can be. workplace where the majority are men. She was always optimistic and that made her see too far from reality.

Jung Hyeon O seemed to me to be a person without emotional responsibility, he does not measure the consequence of his words and actions.
He spent the entire series treating the protagonist badly, when he finds out about her illness, his first thought is that she was with another man and after that, he blames himself for the situation, positioning himself in the position of victim, when there is nothing further away. of that.
He feels pity and guilt, but his actions still feel empty.

In conclusion, they have too much potential in secondary love interests, they missed the opportunity to demonstrate what personal improvement truly is. Where the protagonist does not need a useless man at her side to "easily" overcome her illness.
I don't recommend it, I wouldn't watch it again, although it has quite a few funny scenes, which at times made you forget how bad the drama was, that doesn't mean it was too disappointing.
