Genos doesn't believe in soulmates, or romance of any kind really. And Genos knew 'soulmates'. He sees them all the time, happy couples, small red threads connecting their ring fingers, all happy and lovey-dovey. He doesn't understand the point of it.

Genos sighs and looks down to his cybernetic hand, which had a red thread tied around his ring finger, in a sort of elaborate knot. He let his hand rest at his side, until he felt a tug, and another one, and another one. Then a full on yank.
