Third wheel: A person or thing that serves no useful purpose. An unwanted third party accompanying two people on a date.
If you look at the meaning of that word on the internet, the first that would pop up is exactly that.
I have no idea why the internet thinks that but...!
Being the third wheel is not necessarily useless! You can do it as long as you want to and both parties are comfortable with it.
It's a wonderful thing if you think of it in another way.
You are witnessing love unfold itself right in front of you.
No, not that kind of love. Just the level of middle schoolers.
No! The kind of love that isn't that intimate and explicit! Do middle schoolers go that way at such a young age?!
I haven't even had the chance to even find at least one in my lifetime, but I'm not desperate myself.
Anyways, going back to the main subject.
A third-wheeler is not always useless.
Why do I think of that? Because I am.
How? That will be a story for another time.
Imagine a love unrequited between two people. Their families are well-known and well off with their massive wealth.
You can already guess that I will be friends with them, and of course, I am myself well off with my family, but not as disgustingly wealthy as them.
In this story, I'm only but a mob that will help them attain a good relationship without the distractions and avoid the restrictions they are placed in by their own strict families.
Even if I would be hunted down by hitmen and assassins alike, I will help them no matter what.
You might be asking why I'm going to go so far.
It's because I am their friend, and I am a kind person!
