What we have here is the coupling track to ALLOVER’s single “Mirai ELECTRO”. Actually, I like “Hello Smile” a lot more than its A-side. The promotional video consists of nothing more than off-shot of the girls’ “Mirai ELECTRO” shoot, but there is so much to love. The song itself is a catchy tune with some fun guitar work and a great melody. Like the title suggest, the girls smile through the video and induce wide grins from the viewer. And, who doesn’t want these idols smiling on them for 4:44?
