Ho-ong-i is a notable and prominent Korean producer. He is best known for writing songs with dark, creepy themes, with two of his most notable songs being dark spin-offs of SeeU's demo I=Fantasy via I=Delusion and I=Nightmare. However, the song he is most well known for is the piece Hide and Seek.
A majority of his songs were published between 2012 and 2013, but because there are no longer any official links, it is unclear when several of them were published aside from the years.
