Whether you're dating, married, in a serious relationship, or just curious if you'll end up with your latest crush, there's a TikTok test for it. The trend is called the "Soulmate Test," and it essentially teases you into knowing if your partner's "the one" by using a mathematical equation to come up with your destined soulmate's age. Does it work? Well, it depends on what you want to believe. I tried it with my latest love interest (Justin Bieber) and got both his age and mine — so you know I'm here for it! The test involves your partner's age, your birth year, and the current year to see if you're "meant to be." Pick a partner, plug in the required info, and get into some basic addition and subtraction with this unofficial test! Read up on how to do the soulmate TikTok trend below.
