Song Meaning

The lyrics paint a vivid picture of a reunion between cousins who shared a childhood, now encountering each other as adults. The initial lines establish a sense of nostalgia and surprise at how much the cousin has changed, noting, "大人になったね" (You've grown up). This sets a tone of affectionate observation, tinged with the awkwardness of time passed and unspoken feelings. The core tension arises from the narrator's burgeoning romantic feelings for their cousin, a sentiment that creates a palpable sense of "後ろめたくなる" (feeling ashamed/guilty) when they are near. The repeated invocation of "カズン" (cousin) underscores the forbidden nature of these desires, especially when juxtaposed with imagery like "禁断の果実" (forbidden fruit). This internal conflict between affection and taboo desire drives the emotional weight of the song. The lyrics cleverly play with language, shifting from "カズン" (cousin) to "リーズン" (reason), linking the romantic stirrings to a quest for understanding. The line "恋に似てる その理由(わけ)教えて" (It resembles love, tell me that reason) directly asks for an explanation of these feelings, highlighting the narrator's confusion. The imagery of "庭になる果実" (fruit that grows in the garden) suggests that the object of desire is close at hand, yet still feels illicit, mirroring the familial relationship. Ultimately, the song's power lies in its honest portrayal of complicated emotions within a familiar bond. The narrator's struggle is amplified by the realization that despite their longing, "僕たちはずっとそのまま" (we will always be just like this), emphasizing the unbridgeable gap created by their familial connection and the lingering, unfulfilled desire.
