ONF is ready to come back.
The boys dropped a 'signal message' with the tag '#ㅅㄹㅎㄱㄷㄱㅇ'. Some fans are guessing that it might stand for '사랑하게 될거야', which means "You'll love me". It seems to be confirmed by the letter, which reads, "I'm not sure what happened in the past and future of the other world, but I'm sure of one thing. You'll love me."
Stay tuned until ONF's comeback on February 8th.
