You know the drill: Sundays are dedicated to K-pop history. Today, I’m excited to share a 2.5-generation group with you—AOA! They released their song “Heart Attack (심쿵해)” in 2015.

This highly energetic dance pop hit perfectly captures the physical sensations of falling in love. Here are some lines that exemplify this:

어머나

자꾸만 심쿵해, 널 보면 볼수록

가슴이 쿵쿵대, 나도 모르겠어

“Oh my!

My heart keeps fluttering — the more I look at you,

my heart keeps pounding, I don’t even understand it myself.”
