Bahnus worked with South Korean singer and actress Lee Hyori on her album "H-Logic" which was released on April 12, 2010. This collaboration came as a surprise to many, because Bahnus was introduced as a rookie songwriter, as where Lee Hyori is a senior celebrity. Bahnus was credited as composer for seven out of 14 tracks listed on "H-Logic". All of the songs for which Bahnus received credit were accused of being plagiarized, by netizens.
