[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 watches the door closing and then he can't take it anymore. He falls to the floor, crying and shaking. He's so angry at himself. 


He wants to - no, he needs to forget all about it. 


He takes his phone and searches on his contacts for a name he hasn't thought about for a long time now. 


There are a lot of unread texts, but he notices the most recent one is from today. 


》 Hi, Jay! You’re coming to the party tonight? 


》 Hey! How have you been? We miss you around here. 


》Jay, Minnie asked about you tonight 


》Can’t believe you used to bang her as well! 


》Jay, I’m giving a party tonight. You coming? 


Jack wipes his tears and sends him a reply.
