This story probably shouldn't be called a coming-of-age story. To me, it feels more like a struggle, and it may not be a happy one. Perhaps in other people's eyes, it's a story about an "impossible-to-get-rid-of" ex-girlfriend and a "won't make the first move, won't turn you down, won't take responsibility" scumbag who deserve to be together forever.
Wu You's path to growing up is fierce and stumbling, with her talking to herself all the way. She goes from "When you're young, you should aim for the clouds" to "Success or failure doesn't matter. I just lived one more day." Lin Zixu never asks why, keeps steady, and simply moves forward. So no one knows where the road beneath their feet leads, or whether their paths will meet. The clash between an idealist and a realist sparks no fireworks.
Theme: A nostalgic story about a girl struggling to grow up. What price are you willing to pay for maturity?
"What, you don't want to see me? Then I'm leaving?" Lin Zixu breathed mischievously into Wu You's ear. Wu You tried to run away but was pulled back and held onto his lap. He lowered his head to Wu You's collarbone, not kissing her, nor biting her, but only giving her a light lick. Wu You instantly arched her back, letting out a ticklish cry.
