Soulmark?

Soulmate. The word had an important meaning for Victor nikiforov. To him it meant someone that would be by his side, someone that would love him wholly and unconditionally, and he was certain that his soulmate was the most beautiful, kind, and intelligent being on the planet that would make him happy for the rest of his life.

For Yuri Katsuki it meant that someone was specially chosen for him and that they were surely a flawless human being that he would have to strive to be on the same level. He was doubtful that he could possibly live up to their standards. Or maybe he's the perfect fit for his other half?
