恋爱算个DIO！(Liàn'ài Suàn Gè DIO!)

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

In the song, Xingchen partially sings in Yuezheng Ling's point of view. Being in a romantic relationship with Luo Tianyi, Ling 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. Xingchen is sick of how couples seemingly complain about each other in 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.
