A little bit of Septiplier incoming, so yeah...

Jack and Mark were in the kitchen, bored out of their minds. They had no videos to film, since they both had already filmed and uploaded their videos of the day.
Jack was scrolling through Tumblr while Mark was leaned up against the island, breathing heavily.
"Do you want to get coffee, Sean?" Mark asks, breaking the silence.
"Oh uh, yeah sure! Let me just repost this real quick..." Jack replies, finishing up what he started.
"Come on, it doesn't take all day." Mark laughs as he walks over and kisses Jack's cheek. 
Jack laughs and turns off his phone, then they were off to *insert fancy coffee shop*.

-------------------------------------------------------------

They had arrived about 25 minutes later, they would have arrived earlier but Mark wanted to walk, since he liked exercising so much.
"Finally!" Jack huffs. "We're here!"
"Yeah yeah, I know! You're tired from walking." Mark laughs.
"Well I couldn't say no! You did the puppy dog face! You know that's my weakness." Jack playfully growls, glaring at Mark.
"Oh come on, you know you're cuter." Mark smiles.
Jack blushes and they both go inside. The sudden smell of coffee hit both men like a mallet.
"That is... That is some strong coffee!" Mark remarks.
"Well that means that it's GOOD coffee!" Jack replies.

Jack suddenly felt sick, like a sudden wave of sickness hit him like a mallet, much like the coffee did a few minutes ago.
"Mark." He says, tapping Mark's arm.
"Hmm?" Mark replied.
"I-I'll be right back." Jack stuttered before rushing to the bathroom.
As soon as he made it into the bathroom, he rushed into a stall.

"Oh god..." Jack muttered before heading out of the stall. He went over to the sinks and wiped his mouth off.
He started at himself for a moment, before realizing that all the sudden, his eyes flashed black.
"W-what...?" Jack whispered, before leaning in closer.
Jack sighed, now even more worried, washed his hands and limped back out to meet Mark.
"You okay?" Mark asked.
"I-I'm fine. Just threw up a little, that's all." Jack half-lied.
"Are you sure? You seem terrified." Mark replied, biting his lip. "Maybe it's not a good idea to be here today."
"You're right, let's go." Jack agreed as he bolted out the door. Mark quickly followed.

-------------------------------------------------------------

When they got home, Jack slumped down at the island, hanging his head down and not looking at Mark. Mark sat across from him.
"Sean, are you feeling okay? You're turning really pale." Mark asks as he leans over and brushes Jack's hair out of his face.
Jack didn't answer.
"Jack?" Mark continues, concerned about his boyfriend's sudden change in behaviour.
Jack still didn't move. He was, however, breathing heavily.
Mark got up and walked around the island to face Jack.
He grabbed his face lightly and turned his head to face him, and kissed him. Jack kissed back, but only for a second before giving up.
Mark pulled away and stared into Jack's eyes.
"Sean, you know you can tell me anything right?" Mark bites his lip.
Jack sharply inhales, like he was gonna say something.
But, a fire he could say anything, he started violently coughing. Jack dropped to the floor, and Mark stepped back.
"Mark... Help!" Jack pleads.
Jack was helpless, Mark knew this. He kneeled down beside Jack, he started to cry as he watched his best friend basically die, in a helpless state.
The police would never make it here on time He thought
Jack looked up at Mark one more time. Except this time, Jack's eyes were turning black. A grin was forming on his face.
"J- Sean?" Mark stutters.
"Oh Mark." Anti starts. "Jack is gone. I'm here now."
"W-What?" Mark starts to tear up as he backs up.
"It's such a shame that you didn't say goodbye to your lover before he... Ahem... Died." Anti smiles.
"Jack I know you're still in there... Just... FIGHT!" Mark shouts.
Anti looked at him with a confused look. "Oh, I grew stronger long ago. He couldn't fight anymore."
Anti smiley walked to the counter near the stove and grabbed a knife. "Now Mark, you have two choices. You can either break up with "Jack", or "be with him" if you know what I mean." Anti smiles.
"I-um..." Mark is all Mark could reply.
"Too late." Anti smiles again, and swiftly glides behind Mark, putting the knife up to his neck.
"Any last words before you join Jack?" Anti asks. But he didn't give Mark any chance to speak, and a few seconds later, Anti had slid the knife across Mark's throat.

This isn't my best work. I'm not too proud of it. But at the end of this imagine, Mark is in a better place, he is with Jack now. I don't think I'll do anymore Septiplier-Antisepticeye imagines though.
