I Became a Side character in a BL novel

6-Change

"Please calm down Master Derick! I'm sure the lady drank the poison last night, even Master Arron had seen it!" Teresa cries.

"THEN HOW THE FUCK DID SHE WALK OUT OF THAT ROOM ALIVE IN MORNING!??"

I hear the sound of glass crashing followed by Teresa's scream.

No....no way...

So...don't tell me that was not sleeping medicine but Poison to kill Rosetta!?

I feel a deadly panic rise over my whole body...

I fall down on my knees covering my mouth in shock.

Then the reason why Rosetta wasn't mentioned after the 12th chapter was because....

She died last night in the 12th chapter...!

And just then I hear a voice.

"What are you doing over there?"

I look up to see Arron standing in front of me...

At this point I'm trembling on the ground covering my mouth in shock.

The ruckus inside comes to a stop.

"Who is there outside!?" Derek screams after hearing Arron's voice.

Arron...He saw Rosetta drinking the poison last night.

Then does that mean...

My eyes widen with shock.

Arron walks closer...

My heart starts beating faster again.

"No...! What are you doing? Stay away!" I scream at him.

But Arron looks completely unbothered as he moves closer and closer.

Then comes to a stop right before me.

"Can you move?" He says with his usual smirk.

"Huh?"

"The door...you are blocking it." He points towards the door of the room.

"Ah..." I instantly move my body to the side.

Arron opens the door and casually walks inside.

What the fuck is up with that psycho???

"Hey Arron what is going on? Why is Rosetta still alive?? Didn't she drink the poison last night?" I hear Derek asking him.

"Who knows?" Arron replies.

"What do you mean by that!? Weren't you in her room last night right? You were supposed to make sure she drinks that shit up!" Derick screams.

"Master Derick, please trust me...I saw The Duchess drink the poison last night...." I hear Teresa's whimpering.

"Stop calling her the Duchess! I'm the Lord of this house! There's no way a woman can be superior than me! She deserves to be under my feet!"

When I hear those words from Derick's mouth, I feel a bloody rage burn through my veins.

Balling up my fists, I get up on my feet.

I slam the door open, to find Derick beating Teresa up as Arron stood and watched.

"What the hell do you think you are doing!?" I scream at them.

Derick stops in his tracks to look at me.

"Rosetta...? Since when did you-"

"Everything. I heard everything!"

"Calm down Rosetta! I swear it's not what you think- it was not my plan but his! He wanted to kill you so that this property and wealth would be all his!" Covered in sweat, Derick points towards Arron.
