Have i fallen for you? (SMG34)

Who are you, copycat?

(Author's note: Considering it's the first time i write a story, it would be great for some constructive criticism. Thank you and enjoy.)

In the past few days or months, SMG4 in the castle creating a new video until Mario walked in.
"ES EM GEE FOUR! Mario found a cool video about you!!!"
"Really? I would like to watch it but i need to finish this video real qui-" Four gets interrupted by an explosion.
"What was that?!"SMG4 exclaimed, so Mario and Four go outside to see what that explosion was.
SMG4 saw TWO CHAIN CHOMPS? Of course Four and Mario were scared after that tragic event in Bob-omb Battlefields (you know which one), and so they ran away from the Chain Chomps.
An evil laugh could be heard, coming from the sky.
It was a man, a similar person to SMG4 but.. Different. He had light brown eyes mixed with a vibrant red, long black hair that was tied in a bun and hidden with a purple and black hat, with the text "SMG3"written on it. He had black overalls and a indigo-purple shirt, having the roman number 3 as the logo of his gloves and dark brown shoes. On his face, there was a beautiful black triangular (?) mustache and a little beard, not completely visible.
"Someone help us!"
"Aw, come on! Aren't you two having fun with my friends?" SMG3 chuckled.
SMG4 and Mario were still being chased by the two Chain Chomps when SMG4 entered a cannon, launching him on the roof of the castle. SMG4 started panicking and screamed until he hit the roof of the castle. The man got up and saw a man that looked almost identical to him.
"Who are you, copycat?"
"I'm SMG3, the better and cooler version of you, SMG4.~"
To SMG4, the voice of the cocky man was.. suave? Like, he was sure he liked women, he even had a crush on Meggy for 2 whole years, but he felt his mind not stable when hearing the man in front of him.SMG4 didn't like other men, he always thought he was straight but he fell in love with his dobbleganger as soon as he met him.
(Guess he was bi, bi, bi *insert Bye Bye Bye by idk*)
"You could never replace me SMG3!"
"Oh yes, i can."
"No!"
"Yes!"
"No!"
"Yes!"
"NO!"
"YES!"
"FUCK YOU."
"FUCK YOU."
"FUCK ME."
"..fuck you?"
"...oh god-" SMG4 was blushing when he said that ("fuck me").
