This is a very long story. Kyung Min and Jong Suk were bullied at school, and Kim Chul is like a hero to them. (Days Passed) One day, Chul decided to jump off the roof of the school building and tell their friends about it.(He decided to kill himself because his death would put an end to the bullying of his friends.) However, the night before he jumped from the building, he changed his mind and told Jong Suk that he would not jump, but would act to scare the bullies. But Jong Suk is concerned that it will fail and that things will worsen. So he pushed Chul from the building.
Actually, I am not a fan of slow-burn dramas, but I watched this because of Kim Sung Kyu. At first, it appears to be boring, and I can not even breathe while watching it because the drama makes me impatient. However, I attempted to continue watching until the end. While watching this drama, you will be bored at first, but as you watch more episodes, you will feel more and more interested. It heals me and makes me reflect on my life. Such a beautiful drama.
I will give 8/10.
