A.C.E may be coming back soon.
On April 1st, the boys tweeted that they would be coming back in May and hold a fan concert in June. The second tweet contains the boys practicing with the tags 'ㅋㅂㅇㅅ', which may stand for '컴백연습' or 'comeback practice'. Another tag in the tweet reads "ㄷㅇㅈㅇㄹㄷㅇㅈ", which fans are having a harder time with.
Of course with all things announced on April first, many fans are still cautious on whether to believe it or not. What do you think?
