How to interpret a cumulative spectral decay waterfall plot.
There are a couple of things that I truly love about you. The others, they just make you more perfect in my eyes. But your laugh, when I'm goofy, or the way your gaze pierces through anybody's when they look at me, or how you'd hold our babies in your arms, like they could fit in your pocket, those are the things that make me crazy about you.
The way noona comes out from your lips or how you'd wrap your hands around me and protect me, there's nothing that makes my heart skip beats more. The way you'd hold me, promising of that day when we'll be forever together, that's my dream.
