"Fever" by ENHYPEN is a song about obsession, desire, and longing. The lyrics portray a situation in which someone feels a strong attraction towards another, but cannot act on those feelings. The chorus conveys the idea of being pulled in and consumed by the object of one's obsession, with phrases such as "Like a fever, fever, fever, my heart will burn" and "no matter how much I push you away, my heart is still ablaze". The song conveys the overall feeling of wanting something desperately, even though it may be out of reach.
