my first kdrama! it's worth to watch!

well, this is my first drama/ kdrama in my life. it was popular in my country and i was at elementary school back then, and my housemaid watch this so she asked me to watch together. at that moment i thought it was funny, cute, and sad drama at the same time. i hate ji eun friends, they friends is soo cruel :( anyway it's worth to watch because it's happy ending!
