恋爱算个DIO！(Liàn'ài Suàn Gè DIO!)

Background
"Liàn'ài Suàn Gè DIO!" is an original Chinese VOCALOID song featuring Stardust.

In the song, Stardust partially sings in Yuezheng Ling's point of view. Being in a romantic relationship with Luo Tianyi, she complains about Tianyi's behaviors during their dates, yet she becomes regretful after their break up in a year later as she feels left out in the crowds of couples. Stardust is sick of how couples seemingly to complain about each other in the public but in fact, still love their partners very much. Furthermore, she repetitively sings about the modern cons of romantic partners realistically, as well as the emotional damages love can cost, stating that "being in love means nothing" only out of jealousy, for she — like many others — fails to be in a romantic relationship.
