At first I felt like not watching it. I felt like it would be a mainstream bad boy and good girl romance... but when I started to watch, I realised it's beyond that. It talks about the struggles of each and every character in the story. Every character and how they dealed with their adversities and sorrows. And it also shows three phases of life. The carefree school days when everything seems okay, the slowly growing up days of college when you start falling in love and decide what to do with your career and life, and then the third stage of adulthood and maturity, showing how much the characters change by the time they're grown-ups. I'm in love with this drama because of it's theme of realism.
