Exactly today is the ending of the drama, hence, I am going to speak up my admiration and love to this drama.
The story of your first love being your first boyfriend to being your husband and the father of your child. The main couple were truly a perfect match for each other, they quite compliment each other's personality, and they were each other's happiness and light. What I really like about this drama is the way the female lead keep on documenting her life from the moment that she like the male lead until they become (old), it feels like I am watching someone's handwritten dairy. A truly dream high school life that everyone wanted to experience, a wonderful friendship, a lovely romance, and a youth that you won't forget for the rest of your life. And also, the OST were very beautiful, it really suits the mood of the drama.
Note: The novel of this drama is very recommended to the readers who wants to know more about the inside feelings of the characters.
