The emotional attachment I felt for this drama and characters is beyond comprehension. I cried when they held hands for the first time...i CRIED because they HELD HANDS
At first, I was hesitant to start 'doctor slump', there were so many low and average reviews, people saying it got tiring half through the season or that the characters weren't enjoyable to follow. It's safe to say I disagree with most (if not all) of it. 

For the first time, I felt what those characters were feeling, I was happy when they were happy and sad when they were sad. I cared for them the same way I care for a friend. Watching 'doctor slump' was like living through these people's lives with them, suffering but also fighting for happiness with them. My knowledge of english is not enough to express how I feel about this story. I've never felt so strongly about something in my life lol 

Even though I gave it a 10 and it is definitely my favorite kdrama I've watched so far, it did have a single con, but it was easy to overlook since what I loved about it was way stronger than anything else. My only complaint is the childlike attitude these characters in there 30s have towards a relationship, which happens quite often in kdramas, but it felt exaggerated in this one (they kissed like 2 times and got shy about it even after months of dating, like bffr).  With this out of the way, everything else was everything I needed it to be. I liked every single character, bad or good, they had a purpose to be there, and I didn't feel the need to skip a single second of it. I enjoyed every scene with Haneul's family and with 2FL and 2ML, and as someone who tends to find side stories too boring, i was surprised and satisfied. 

The ending was also satisfying. I'm always scared to start a new kdrama and be disappointed by the last episode (business proposal, im looking at you).
