Another Manhwa manga I have on my bucket list to read. I was planning to read this on kindle but recently it was reduced from £6 to 0.89p. I bought it immediately for 0.89p. It is good because I want to read something different and a manhwa manga that will be interesting to talk about for this podcast. 
I reviewed Hyperventilation and I thought it was really good.

I thought 'On or Off' is average in my personal opinion. I thought the artwork was flat. I was hoping to feel the chemistry between the characters. I felt story dragged on a bit too much without something interesting scenarios. I was a bit uncomfortable with Kang Daehyung sorta taking advantage of Ahn Yiyoung. He knows that Yiyoung is desperate to promote his game and he agrees to do anything.
