Temporary Bliss

"I love you, Iris. You'll be mine, won't you?"
"I-... I don't know."

Imagine living in a world where soulmates were so rare that, they were considered a myth. Someone could find their soulmate, but would never even know that they had found them. The only hint that they are given is a sudden deep attraction towards that person after they have shared intimacy. After soulmates have shared intimacy... if they are apart for too long, they'll begin to become weaker and weaker until they join with their soulmate again.
However, if having just one soulmate was so rare that it was classified as a myth... what would happen if a person had two soulmates at the exact same time, where the odds for that are one to a trillion?
