Meh she sang 80% of SISTAR so close enough xD - Okay so I'm gonna be frank about this, GFriend and TWICE released title tracks that weren't really to my liking, this time. I tried listening to the songs a little more than usual to see if it might spark some feelings but, alas, it didn't. My two ultimate bias groups came back this summer and I didn't love it - Now, on this song! I LOVE IT! I really really love it! It's so good omg! Hyolyn really saved summer Kpop for me! I'm blown away by the fact that I like it so much. I'm definitely gonna be listening to this over the summer, a lot! Oh and well, I'll be bopping to Vacation and Chillax too ^^ - Stream Hyolyn! Stan Hyolyn!
