I absolutely LOOOOOOOVE this drama! -=+STORY+=- I thought the plot was great. This drama dealt with the sensitive subject of mental illnesses, which most dramas can't pull off. The story starts out with a good introduction, and you know immediately what each character is like. The rising action is great, it shows the growing chemistry of the actors/characters while at the same time giving hints here and there about present and future events. WOW! The climax! It was such a brilliant way to turn things around. The falling action was also great, as it showed how characters endured certain events. The resolution was also the perfect way to tie up the story. The one thing that slightly ticked me off was Hae Soo's short tempered personality, but that can be overlooked. -=+ACTING/CAST+=- OH MY GOSH. This cast was PERFECT! I could totally feel the chemistry between the characters, and the acting was so natural that I felt like I was watching them right before my eyes. Jo In Sung and Gong Hyo Jin didn't disappoint and Kwang Soo and Dong Il were great supporting characters. In this drama, we also have a newcomer, Do Kyungsoo (D.O of EXO). I was really surprised by his performance, especially for a rookie. The characters were well developed, and I liked how all of them had their flaws. -=+MUSIC+=- Wow, this may be the best OST I have ever heard in a drama! Unlike other dramas, IOTL actually had english songs in the soundtrack. Most of the music was happy and joyous, while the more mellow tracks still had a great impression. I downloaded like half the songs in this soundtrack, and I could listen to it on repeat for a long time. -=+REWATCH VALUE+=- 10/10 I am definitely considering watching this masterpiece again. I had so many great feelings while watching this. It made me laugh, cry, squeal and so much more! At first I had high expectations of this drama, and it surely lived up to that. If you haven't watched it already I BEG OF YOU TO PICK IT UP! IT WON'T DISAPPOINT!
