Before I dive into why I wrote a headline that way, I'd like to share the positives of this drama:
- The intro to mid plot are awesome. Both leads are tangled in an unfortunate, yet strange relationship where one is the family of the donor, and one is the family of the donor receiver.
- The entire genre and story summary is very promising - as it is supposed to be a love story between 2 successful, smart individuals from teen years.
- The friendship story is always my go-to, and love a strong and solid friendship moments.
- The chemistry between the 2 leads are very cute and refreshing.
- Almost all the characters are likeable, which is rare in the drama world.
- As an additional, the leads are very good looking people. :)

Now let's go for the negatives: (entirely based on my opinion and taste as a watcher)
- The mid-to-last episodes are totally different as it felt like a different drama compared to the first episodes. What I mean especially is how the female lead is breaking her own character. She felt like a stranger when I watched her in mid-to-end episodes.
- Female lead character is poorly developed. Every drama leads needs to have a character development. Especially in this genre where the entire story is about journey to adulthood. Yet, it felt like the female lead character became worse each episode. For instance, where the female lead misunderstood the situation and acted immaturely.
- For the side characters too. Male lead parents are supposed to be open-minded and kind. But for some reason, the writer decided to turn the father into someone very petty and low, where he manipulated female lead to convince male lead going to different university of dad's choice. It's totally out of character and doesn't make any sense whatsoever.
- The side couple story is not very interesting enough to watch. I can't comment on that one since I skipped almost all of the side couple's scenes, but it isn't convincing enough for me to actually watch the side character's story.
- Would like to see more on how smart the female lead is. Here is my issue, female leads are sometimes or often portrayed as weaker than men, and this is a great example of that. The entirety of this story is supposed to be how female lead is smart and hard-working enough to become a doctor in the future, and yet, all I see is a female who likes to play around and let the emotions come to her.
- I feel like the plot twist is very unrealistic too. What I mean is when the female lead's parents were attacked, which happened to be at the same time when the female lead was about to take national examination. Thus she had no choice but to retreat the test. I know dramas can be unrealistic for entertainment purposes, but it just left a bad taste as a viewer.
