N will be singing a solo, Korean version of "Cactus", which VIXX released in Japanese back in September of last year. The song was written and composed by N. 

N's collaboration single is with the Korean branch of 'Habitat for Humanity', as well as with donation platform 'Happy Bean'. The idol also held a charity project with 'Happy Bean' last year, selling eco-bags and eco-pouches to raise funds for a disabled youth orchestra.

You can listen to N's solo version of "Cactus" on February 2 at 6PM KST. Click here for N's 'Habitat' page on 'Happy Bean'.
