The opening track, "비눗방울", retains the closest sound to Seoulight, with a smooth vocal delivery from Neon Bunny complete with overdubbing and practical instruments. Of course the guitar and bass are played in a much more funky manner than on Seoulight and combined with the bright synth hits and dance beats, it's clear that Neon Bunny and producer Cliff Lin are moving the Bunny in a different genre direction. This is obvious from the deep opening bassline on "Plastic Heart", which pairs that bass, dance beats, and New Wave synths with Bunny effecting a more whispery vocal style, not unlike that of fellow electropop singer I Yungjin of Casker.
Happy Ending's single, "왕자님" fulfills the promise of New Wave synthpop delights with a series of synth hits and handclaps atop that same deep verving bassline as Neon Bunny sings a rather blistering brush off of a rich guy that's trying to win her over with his status. Featuring a gurgling synth instrumental break and a perfectly addictive chorus, it's certainly not the only track worth making a single on the EP, but it is obviously the catchiest here.
Happy Ending closes with "첫사랑", continuing with all the same elements (synth, claps, deep synth bass) that help drive the rest of the EP, but especially lays down on the synths, using vibrating synth to add further energy to the bass. It, like the opening track, also capitalizes on the Bunny's capacity for sustained melodies.
And then, fifteen minutes after the EP started, it closes. It's a bite-sized exposure to what Neon Bunny is capable of doing when injected with a New Wave verve, a dose of sass, and a dance beat and she delivers pretty well. In fact, Happy Ending's most disappointing characteristic is that when it ends, I simply want more, which I think actually doubles as praise. And while I loved Seoulight and the change in genre caught me a little off guard at first, eventually, I came to realize that Neon Bunny is just as much in her own element here making synthpop as she was making pop rock. Which is to say that I love Happy Ending too and I'm looking forward to seeing what the noble Bunny might come up with next. 9/10
