These are t-shirts that you buy as a pair and the closer you get to the other person wearing the T-shirt the more hearts light up on the T-Shirt. Sure they are Zelda hearts for nerds that know but hey, get these in a his and hers and your non-nerd partner never need know
During your normal activities two and a half pixelated hearts will light up on your shirt. Hey… you’re depressed and in need of a recharge. But get within hugging distance of your significant other wearing the matching shirt and suddenly the hearts on both of your shirts start to light up until you’re fully powered up. Go too far astray from the source of your affections and you’ll drop back down to two and a half hearts again. Got it?
