(More or less, this is a story about two troubled people learning to love and save each other.)
Everyone at Linyi University knows Su Yu is Gu Zhou's girlfriend, but no one thinks they'll last. Gu Zhou has a string of girlfriends, and the two of them are worlds apart. Su Yu thinks so too. She does whatever she likes while they're together, then cuts things off cleanly when they break up.
Later, Gu Zhou asks her why she doesn't want him anymore. She says it's because there's something wrong with her.
"Perfect, there's something wrong with me too. Want to try dating again?"
