君はできない子 (kimi wa dekinai ko)

The song "Kimi Wa Dekinai Ko" by VOCALOID, a singing voice synthesizer software, presents a haunting narrative that delves into themes of dependency, inadequacy, and abandonment. The lyrics paint a picture of a person who is described as utterly incapable ('dekinai' meaning 'cannot do' in Japanese) and dependent on the singer for survival. The repeated phrase 'dekinai ko' (incapable child) emphasizes the helplessness of the individual being sung about. The song uses a lullaby-like tone, which adds a layer of irony to the otherwise dark and pitiful description of the subject's condition.

As the song progresses, the singer's protective and almost possessive attitude towards the 'incapable child' becomes apparent. The use of derogatory terms and the listing of flaws suggest a twisted form of affection, where the singer finds purpose in being the caretaker. However, the relationship is not one of mutual respect but rather of control and dependency. The singer's identity is so intertwined with their role as a protector that they cannot fathom existence without the other person's neediness.

The final verses reveal a twist: the 'incapable child' eventually leaves, suggesting a growth or change that the singer did not anticipate. The singer is left alone, realizing that they are now the 'dekinai ko,' unable to cope without the person they once deemed helpless. This reversal highlights the codependent nature of their relationship and the singer's own vulnerability. The song ends with a longing for the past and a realization of the singer's own inadequacy, loneliness, and desire for a chance to turn back time.
