This song by HAKONIWA RILY portrays the narrator’s growing suspicion of a partner’s infidelity, the sense of wonder at their behavior, and the shifting emotions when evidence is found.

The gradual confrontation, and the image of cutting one’s hair with scissors after the affair is exposed to sever lingering attachment, conveys a kind of inner darkness.

The contrast between the gentle, soothing atmosphere of the sound and the starkness of the lyrics is striking.

In the section depicting the exact moment the cheating is revealed, the arrangement drops all sounds except the vocal, further emphasizing the darker emotions.

The track is peppered with elements that heighten the sense of fear—like the scissor sounds referenced in the title and the cute vocal timbre.
