I can't figure you out at all
So when I'm not aware at all
There's no possible way
You can steal my heart
It could be a grumpy smile
Or it could be dusk on a Sunday
Or it could be a period with nothing but exams
Or it could be a melancholinist called you
I keep thinking to myself that trying to act tough
And confronting things without a plan won't get me anything in the end
Because I'm the kind of girl
Who'd lock myself up into a tight ball
Whenever I need just a little courage
I can't figure you out at all
So when I'm not aware at all
There's no possible way
You can steal my heart
You don't notice anything at all
So I don't care about you, don't care about you at all
Don't you "hey hey" me and stop smiling like that
Or I'll lose my sleep again
Tomorrow, I wonder if I'll be the same old me,
The unsociable, silent, and uncute girl
Ever since you appeared in that dream,
I haven't been honest to myself
Because I can't figure you out at all
Without even realizing,
The one who was trying to steal your heart
Was me all along
It's the phase I'm in
I want to drown, oh this sweet melancholy
