[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

Vince feels empty. He shouldn't feel this way. 


He's better now, he's healthy, and he managed to come back to college. 


He's been hanging out with Seven a lot more, too. He's dating this guy named Luke, a doctor that works with him at the hospital, and he and Vince clicked off really well and instanltly became friends as well. He was happy his best friend's soulmate was such a wonderful person. 


He doesn't tell anyone he found his soulmate. Theo knows, but they don't talk about it. He’s greatful that the other doesn’t bring it up. 


His mother asks him one time. She finds it weird that Vince’s episodes stopped out of a sudden. Vince lies to her and tells her he doesn't know anything either. 


He and Theo still hang out, sometimes with Noah and Keith as well. Vince is amazed by the fact that his friend has not only one, but two soulmates who love him so much.
