Kiss Kiss by Kim Hyun Jung
I'm not a fan of Kim Hyun Jung. In fact, I used to dislike him :p but since my sis kept telling me that this is a good song, I tried to listen to it. Then hey, it is a simple yet good song! And even though it sounds sweet, it's actually a bitter song, they said. So, a soundtrack for a sad summer, we can call it?
Maybe those people are right. You shouldn't extremely hate something. You might end up loving it at the end :p
