"Luv" is a throwback track similar in theory to Apink's 2011 single "MyMy" recalled early '00s bubblegum pop and 2012's "NoNoNo" touched on '80s synth-pop notes. Despite the glossy production and funky dance breaks, the girls are singing about lost love, rather than their signature cheery lyrics.
Showing a new side of themselves lyrically, Apink's members remember time spent with their ex-lovers and the safety felt with them while wondering if they reminisce over such feelings as well. Melody-wise, "Luv" has a brightness to it with a hint of melancholy in the girls' voices.
While it's not true for the entire song, Apink also slightly mixes up their formula in terms of line distribution here. While main vocalists Eunji and Bomi have almost always handled the choruses, member Chorong gets a chance to shine on the final section.
The accompanying video plays more to the sorrowful side of the song as the girls longingly sing to the camera with crystal stickers stuck near their eyelids, looking a bit like tear drops. Like any Apink visual, there's loads of glam shots and cute dance moves, but it's all presented with a fall-themed color palette with whites, grays, black and beiges instead of the usual pinks, blues and yellows we're used to seeing from the band.
Mixing a sad subject with a vintage, throwback beat makes "Luv" a rather multidimensional track while showing that Apink can make a few tweaks to their usual formula and still provide the aspects that help them continue to stand out from other acts.
