*죽겠네 is an expression that can be translated in many ways --- it's usually used when you don't know what to do with yourself or you're going crazy because you're too happy, mad, sad, etc. In this song, it means, "I like you so much that you're driving me crazy"
I don't know what to do with myself You're beautiful, even when you don't smile I'm so happy by just looking at you You drive me crazy Even the sound of your snore sounds cute You smell sweet, even when you stink You radiate even when you didn't shower You drive me crazy
What if I really go crazy? What if I stop breathing all of a sudden? The sleep in your eyes to me is It's so nice, so nice, so nice The hole in your tights to me is It's so nice, so nice, so nice A second, a minute is like a jewel to me Don't have the time to fight because We don't even have enough time to love You drive me crazy
What if I really go crazy? What if I stop breathing all of a sudden? The seaweed on your teeth to me is It's so nice, so nice, so nice Even your small boobs to me is It's so nice, so nice, so nice I don't know what to do with myself You're beautiful, even when you don't smile I'm so happy by just looking at you You drive me crazy You drive me crazy
