[10] In "Mild" version, the members shows their chic charms under a calm blue tone background in a black and white modern look to create a dreamy atmosphere.
The closing track, "Boy In Time" is a "sweeter and more serious love story" solo song by Hui as a gift for fans who miss him after leaving for military service.
She stated that "the two songs hint at a more low-key direction for the boyband, who are known for their high-octane, anthemic releases – one that’s infinitely more interesting than this album’s title track."
She also wrote that "That's Me" track "features questionable use of Auto-Tune alongside a strange combination of electro and '80s funk-pop that confuses as much as it frustrates" and remarked that the closing song "Boy In Time", a "powerful and emotional solo farewell from Hui".
