W’s chords sounds like playful but I think their version a bit more sounds darker and maybe because of Seungyoon heavy voice on vocal make it feels a bit more deep and soulful meanwhile BB’s version had a lot of taste with R&B n jazzy vibe on this Japanese arrangement but the vibe is more light and looks like the tempo itself a bit faster than W’s version. Also the biggest differences is the vocal parts. BB had a lot of light voices in the higher notes meanwhile W sounds like heavier but playful n comfortable at the middle of tempo. So, yeah hits differently from the original.
