Erwin has stretch marks because he grew so quickly when he hit puberty. They’re white and faded by now, along the inside of his thighs, his hips and all over his ass. When Levi finds them, his eyes go wide and he asks if those are scars. Erwin explains quietly, not sure how Levi will react.
Levi traces his fingers along them, doesn’t speak for some time. Then he leans in to kiss all of them, every single one, and says:
“They look like little shooting stars. I like them.”
