MTL - Start with Batman - Chapter 4 next task

Xia Wan entered an ancient Mary Sue campus novel and became a cannon fodder female supporting role who had a marriage contract with the male protagonist F1.
F1 thinks she gets in the way because he likes the heroine.
Because F2 has a crush on the heroine, he thinks she is superfluous.
F3 finds her troublesome because she needs a female lead.
F4…I’m still working as an exchange student abroad, so I won’t be able to play for a while.
In order to avoid becoming a suspect in the future.
On the first day of transferring to this school, Xia Wan stood on the podium and introduced herself, “Hello everyone, I’m Xia Wan’s younger brother!”
*
The system told Xia Wan that there are two ways to live, to gain love or friendship from F4.
Xia Wan chose the latter without hesitation.
On the first day of disguising as a man, Xia Wan gave water to the grumpy F1, and a rainbow fart output touted his skills as a dog.
On the tenth day of disguising as a man, Xia Wan helped the gentle school god F2 avoid his crazy suitors.
Fifteen days when she disguised herself as a man, Xia Wan gave the dandy F3 sincere care and help.
…
When F4 returned to China, he found that the position that should have belonged to him had been replaced by someone.
And his three close brothers fought over who was Xia Wan’s best friend.
F4: ? ? ?
#Our F4 seems to be over#
Xia Wan:OAO
#What do you see me doing? I don’t know anything! #
Thanks for the cover @salt lemon.

- Description from novelbuddy

Cole is a novel author.

He enjoys writing novels and even reading other's works as well.

But that's just it.

Reading and writing novels.

Those are the only things Cole enjoyed in his whole life.

And as the time goes by, even doing those are becoming boring for him.

But then one day, Cole recieved a mail!

The mail said that his work has been chosen!

In a contest? No.

Cole's novel was chosen by a Higher Being to make it a reality!

“What kind of bullshit is this?”

“Whoever sent this must have few loose screws in their head.”

Though, Cole didn't took the mail seriously.

“Huh?”

That is until he was sent in to his own novel!

Cole became Raven Obadiah of his novel!

Who is Raven Obadiah?

No Idea! He's just an Extra in the novel!

...Or is he really just an Extra?

I was a genius in the Earthen Plane.
