I lost my wife early and have been raising my daughter on my own. Recently, my daughter has been going through puberty and she has been saying things like I smell and I'm dirty, but I've been playing the role of the "ideal father" so that she doesn't have to worry. Then, one day, I met my daughter's best friend, Mai. To my surprise, she started to show affection for me. At first I resisted, but as a man I couldn't help it... and so we started a relationship that I must never let my daughter find out about.
