BoA pointed out the mistake via Instagram on April 25. She shared a short clip of her upcoming release on 'SM Station' season 2 and wrote, "#Station #BoA #SpringRain 2017.04.28 6PM (KST) But why were they not able to distinguish the lowercase and capital letters? Hul~~~~~ Aren't I BoA? Please check before you upload~~"
That's right, it's BoA, not BOA!
