As promised, here is the next part of my two-part nugu boy groups comeback review, featuring Speed, Boys Republic and High4. Out of these three groups the only one I've ever written about before is High4 when they had their comeback in January with "Day By Day", and although I was left with a good impression I wasn't 100% satisfied. The other two are completely unknown to me, and although both of them have been around a while they never sparked my interest before.
