Keima-sensei's : How to maintain a love triangle

What I love about anime is that you get to learn a lot of things. Today we'll learn about Keima-sensei's Delta Force of love.
The 3 "F"s  to maintain a love triangle.
 1. Follow

2.Foolish (or be a fool)

3. Fukanzenna Ketsumatsu (Incomplete Closure)

Excellent advice Keima-sama. But aren't these the same tips for two-timing? Anyway if it all doesn't make sense please read Chapter 126 of  The World God Only Knows Manga. I can't wait for the anime's second season!
