After he met her, he realized she was the meaning of his life. A sudden car accident sends An Ran back in time, straight into a classroom in her sophomore year of high school. Her teacher punishes her by making her clean the boys' restroom, where she happens upon Wu Yang being bullied. Overflowing with a sense of justice, An Ran kindly rescues him. From then on, Wu Yang sticks to An Ran like glue, following her everywhere. No matter how hard she tries, she can't shake him off. He even skips a grade just to join her class. "An Ran-jiejie, do you need a little sidekick? I won't charge you!" An Ran looks at him with disdain. "Get lost! You're a pig if you can't even protect yourself. What use would I have for you?" "That's only because I hadn't met you before! Meeting you made me brave! (Jiejie, praise me!)" "…" "You saved me once, so I'll protect you for life, Jiejie! Don't you dare reject me! Pinky promise!" "As long as you need me, I'll always be here." "I just really like you, Jiejie. I fell for you at first sight, and was completely smitten at second." Missing you feels like moonlight; seeing you feels like sunshine; waiting for you feels like the dawn. The sun shines at its brightest, and you carry its radiant glow. I'll love you for a long, long time, until the end of the world.
