The physics of the Third Wheel

Once again, this is another one of those post I have hoarded up for when I reach a dry spell. But this one could be pretty interesting (I hope).

The reason behind this post is simple enough. A couple of months back, I read a manga called GirlXGirlXBoy. I’m not sure if it’s popular or well-known but I definitely liked it. And a couple of weeks ago, another manga I was reading, Kimo Koi Limit, ended. And these two manga have 1 thing in common (well, 2 actually. They’re both generally Yuri). They both had a “third wheel” character that aided the progress of the main couple’s relationship. And I have always pitied this one poor person.
