[BL] Due to a rare condition, Vince’s end of the red string of fate is tied around his neck, while his soulmate's, Jack, is tied around his finger, like it’s supposed to be.

Theory says that if they "sleep" with someone that isn’t their soulmate, the string tightens on the other end, letting your soulmate know exactly what you are doing.
When Jack feels his string tightening, he feels heartbroken, and starts to sleep around with everybody as revenge, not knowing Vince was a victim of abuse.

When they finally meet, Vince is already suffocating.

Love and fate's hopes for humanity were way too high and all they got was disappointment

Singularity: The Red String Around Your Neck

Jack and Vince are both outside the hospital building now. 


They're walking in silence, side by side, 


A wind passes by and Vince smiles at the sensation, enjoying the feeling of being outside after so long. 


Jack's phone starts buzzing. It's Theo 


“Hi Jack. How is everything? Is Vince okay? Did something happen?” Theo asks, voice unsteady. 


“Everything is okay.” He smiles. “The doctor said Vince can go home.” 


“We’re outside waiting for Mrs. Taylor to come pick him up. He said hello to you!” 


“That’s amazing, Jack. Tell him I said hello, too.” 


Vince sees Mrs. Taylor and waves. She walks to them. 


“I gotta go, Theo. We’re going home.” 


Mrs. Taylor gets closer and hugs Vince.
